Synthesis and heteroatom-hydrogen activation studies of the anionic zirconocene trihydride [Cp*(2)ZrH(3)](-).
No full textSynthetic routes to an anionic zirconocene trihydride complex [Cp*2ZrH3]- 67 have been investigated. The original synthetic strategy involved the addition of KH or LiH to the zirconocene dihydride [Cp*2ZrH2] 10. Though this method proved to be reliable, generating the dihydride staring material was plagued by poor yields. An alternative synthetic route involved oxidative addition of dihydrogen to Zr(II) species generated in situ via the Negishi method. Again this allowed for the isolation of [Cp*2ZrH3]- 67 but it was contaminated with LiCl. A two-step process was eventually developed allowing for the facile high yielding synthesis of the first zirconocene trihydride anion 67. Initial reactivity studies of 67 were directed at exploring the nature of the hydride ligand. Analogies were drawn between the reactivity of 67 and the parent complex [Cp*2ZrH2] 10.

The characterization and chemistry of {\it mono\/}- and {\it bis\/}-cyclopentadienyl titanium thiolates.
No full textThe reactions of Cp\rm\sb2TiCl\sb2 with the dithiols, HS(CH\sb2)\sb{\rm n}SH (n = 2, 3) in the presence of imidazole proceed with formation of imidazoleHCl affording relatively insoluble titanocene dithiolate derivatives 2.1 and 2.2 respectively. Alternatively, 2.2 can be prepared by the reaction of Cp\rm\sb2TiPh\sb2 with dithiol. The spectroscopic and analytical data are consistent with the formulation of 2.1 and 2.2 as the bimetallic compounds Cp\rm\sb2Ti(\mu-S(CH\sb2)\sb{\rm n}\rm S)\sb2TiCp\sb2 (n = 2 2.1, n = 3 2.2).

Group 8-10 complexes of pyridyl-phosphinimines and chiral bis-diiminophosphoranes.
No full textA group of exocyclic pyridyl-phosphinimine ligands have been prepared in excellent yields by oxidizing trip henylphosphine with 2-azidomethylpyridines. These ligands reacted with group 8--10 transition metals to form various late transition metal complexes (e.g. [Ph3P=NCH2(2-Py)]NiBr 2 36) which have been characterized and evaluated for olefin polymerization activity. We found that these complexes are not active for ethylene polymerization or oligomerization. In a similar sense, nickel complexes 55 and 56 were synthesized by the reaction of nickel dihalide with a chiral bis-diiminophosphorane ligands. The corresponding ligand was prepared by deprotonation of R-2,2' -diamino-1,1'-binaphthalenetriphenyldibromide by a strong base. The complexes were seemed to be inactive for ethylene polymerization, and were therefore not tested for alpha-olefins polymerization.Dept. of Chemistry and Biochemistry.

Perspektywy rozwoju biotechnologii w Polsce
No full textWażnym czynnikiem rozwoju biotechnologii w Polsce są nowoczesne badania naukowe. Artykuł Perspektywy rozwoju biotechnologii w Polsce zwraca uwagę na to, że wiedza z zakresu nauk biologicznych i medycznych przyczynia się do większej konkurencyjności zarówno ośrodków naukowych i badawczych, jak i przedsiębiorstw. Biotechnologiczne projekty naukowo–badawcze realizowane w Polsce nie tworzą jeszcze podstaw do wytwarzania produktów biotechnologicznych w takim zakresie, by polskie przedsiębiorstwa mogły konkurować na rynku międzynarodowych. Jedną z przyczyn, którą analizuje Autor w artykule, jest niewystarczające inwestowanie w rozwój nauki i wsparcie dla małych i średnich firm w sektorze biotechnologii. MSP są najważniejszym elementem rozwoju tego sektora, ponieważ koncentrują się na tworzeniu i rozwoju nowoczesnych produktów biotechnologicznych. Artykuł został podzielony na dwie części: Szanse rozwoju nowoczesnej gospodarki w Polsce bez biotechnologii oraz Edukacja i projekty B+R. Autor finalizuje rozważania, pokazując pozytywny scenariusz dla rozwoju sektora biotechnologicznego w Polsce.Biotechnology uses biological processes in the development of technology or manufacture of a product. It is forecasted that Polish biotechnology industry will exceed very quickly. The technology and science parks in Poland have invested millions Euros to build new laboratories. Polish market is fuelled by increased R&D funding, central and regional governments initiatives. The article on “Polish perspectives of biotechnology development” identifies significant factors for biotechnology project development. It also indicates the examples of government biotechnology initiatives in the world. The author focuses on the statistical analysis of the research and development projects conducted by Polish scientist in scientific laboratories. His main conclusion is that biotechnology will be very important in developing Poland, Polish universities, research and development organizations.Udostępnienie publikacji Wydawnictwa Uniwersytetu Łódzkiego finansowane w ramach projektu „Doskonałość naukowa kluczem do doskonałości kształcenia”.

NJBankers 2015 Economic Survey: Final Analysis and Report of Survey Findings
No full textThis is the fifth annual Economic Survey. The survey inquires about national and state current economic assessments, as well as six-month projections; expectations about long-term and short-term interest rates; commercial real estate submarket and loan demand; and residential loan and refinance demand. The survey also explores real estate values, currently and expected, as well as a set of negative indicators and common obstacles to lending. The survey series probes metrics about the national, state, and banking market economies in order to better understand, and, in turn, better facilitate the growth, development, and common interests of the banking sector in the state of New Jersey. Conducted by the Bloustein Center for Survey Research (BCSR) under the direction of James Hughes, Marc Weiner and BCSR senior research specialist Orin Puniello,Conducted for New Jersey Bankers Association"January 2015

Metallated group IX and group X phosphinimine complexes.
No full textThe focus of this research has been the preparation of late transition metal phosphinimine complexes. The thesis herein describes the synthesis of a series of monomeric Group IX phosphinimine complexes. [RhCOD(o-C 6H4PPh2NR)] (R = 2,6-C6H3(CH 3)2 44, 2,6-C6H3 iPr2 45, 3,5-C6H3(CH 3)2 46 and Ph 47) were prepared via salt metathesis under mild conditions. The analogous complexes [Rh( o-C6H4PPh2NPh)(Ph2PCH 2CH2PPh2)] 52 and [IrCOD( o-C6H4PPh2NPh)] 53 were also readily prepared by similar methods. Reactivity studies were performed on these complexes. Unexpectedly, complexes 46, 47, 52 and 53 underwent oxidative addition of methylene chloride. However, when steric bulk was introduced on the 2,6-positions of the N-phenyl ring (compounds 44 and 45), oxidative addition of CH2Cl2 was not observed. The reaction of Group X transition metals with phosphinimine ligands was also explored. Attempts to coordinate [Li(o-C6H 4PPh2NR)]2·Et2O (R = SiMe 3 61 and tBu 62) to Group X transition metals proved to be unsuccessful due to steric congestion. However, transmetallation did occur when less bulky phosphinimine ligands were used, such as, [Li(o-C6H4PPh2NR)] 2·Et2O (R = Ph 63 and 3,5-C6H 3(CH3)2 66). The Group X phosphinimine complexes described herein, [Ni(o-C6H4PPh 2NR)2] (R = Ph 67 and 3,5-C6H 3(CH3)2 68) and [Pd(o-C 6H4PPh2NPh)2] 69, were bis-ligand type complexes.Dept. of Chemistry and Biochemistry.
