Regioselective syntheses of fully-substituted 1,2,3-triazoles: the CuAAC/C–H bond functionalization nexus
No full textRegioselective syntheses of 1,4,5-trisubstituted 1,2,3- triazoles were accomplished by three different strategies, relying on (i) the interception of stoichiometrically formed 5-cuprated-1,2,3-triazoles, (ii) the use of stoichiometrically functionalized alkynes or (iii) catalytic C-H bond functionalizations. This perspective article summarizes progress in this research area until June 2010.DFG; DAA

No full textChemInform Abstract: Direct C—H Bond Arylations and Alkenylations with Phenol‐Derived Fluorine‐Free Electrophiles
No full textSignificant progress has been accomplished in direct C-H bond arylations of arenes and heteroarenes with readily accessible, inexpensive phenol derivatives. Thus, ruthenium biscarboxylate complexes and inexpensive cobalt compounds allowed for challenging C-H bond derivatizations of arenes. Further, palladium, nickel and cobalt catalysts set the stage for step-economical C-H/C-O bond functionalization with electron-rich as well as electron-deficient heteroarenes

Bibliographics for the 983 eprints in the live archives of E-LIS : trends and status report up to 7th July 2004, based on author-self-archiving metadata
No full textThe priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes
Automatically extracting interaction and app data from mobile application traces
No full textIn this research, we used an existing system to collect mobile interaction traces and extract meaningful information in terms of interaction data, apps, and layout information and complexity of mobile apps. The preeminent driving force for this research was to come up with a system that is scalable and can be used to extract interactions and layouts from mobile apps, as well as enable us to make claims about the complexity of mobile apps and the flows that they offer. Throughout the course of this research, we collected Android mobile interaction traces and presented a technique which enables extraction of frequent interactive elements from the traces in an unsupervised manner using neural network auto-encoders and k-means clustering. The research work also enables us to find similar layouts across apps and make claims about the location of some of these interactive elements. This research provides a scalable data-driven approach to finding clusters of frequent icons and interactions as well as layouts.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01The student, Abhishek Harish, accepted the attached license on 2016-04-14 at 15:22.The student, Abhishek Harish, submitted this Thesis for approval on 2016-04-14 at 15:27.This Thesis was approved for publication on 2016-04-15 at 13:54.DSpace SAF Submission Ingestion Package generated from Vireo submission #9229 on 2016-07-07 at 13:49:16Made available in DSpace on 2016-07-07T20:27:21Z (GMT).

Copper-catalyzed CuAAC/intramolecular C–H arylation sequence: Synthesis of annulated 1,2,3-triazoles
No full textStep-economical syntheses of annulated 1,2,3-triazoles were accomplished through copper-catalyzed intramolecular direct arylations in sustainable one-pot reactions. Thus, catalyzed cascade reactions involving [3 + 2]-azide–alkyne cycloadditions (CuAAC) and C–H bond functionalizations provided direct access to fully substituted 1,2,3-triazoles with excellent chemo- and regioselectivities. Likewise, the optimized catalytic system proved applicable to the direct preparation of 1,2-diarylated azoles through a one-pot C–H/N–H arylation reaction
ChemInform Abstract: Well‐Defined Ruthenium(II) Carboxylate as Catalyst for Direct C—H/C—O Bond Arylations with Phenols in Water.
No full textThe ruthenium(II) carboxylate complex [Ru(O(2)CMes)(2)(p-cymene)] enabled efficient direct arylations of unactivated C-H bonds with easily available, inexpensive phenols. Extraordinary chemoselectivity of the well-defined ruthenium catalyst set the stage for challenging C-H/C-O bond functionalizations to occur under solvent-free conditions as well as in water, and allowed first direct C-H bond arylations with user-friendly diaryl sulfates as electrophiles.DFG; DAA
Demonetization\u27s Effects: A Study Focused on the Ambala District HARISH KUMAR
No full textDemonetization is the procedure of eliminating a monetary unit\u27s lawful tender position. Eachoccasion the monetary system is modified, demonetization is required. A new currency unit must be introduced to replace the previous one. 200 participants were randomly chosen for samples from the Haryana district of Ambala. Four factors—gender, age, annual income, and occupation—have been found to significantly correlate with the effects of devaluation. Demonetization\u27s role in destroying black money came in first place among respondents\u27 rankings, which were then followed by the elimination of social evils including terrorism and corruption
