Silver-Mediated Direct sp(3) C-H Bond Functionalization
No full textDirect sp(3) C-H bond functionalization is an efficient, straightforward, and powerful method to construct new C-X (X = C, N, F, S) bonds from nonfunctionalized aliphatic motif of organic molecules, which has been used in late-stage modification of complex molecules. In this chapter, the recent developments of silver-mediated direct sp(3) C-H functionalizations are reviewed, categorized by C-C bond formation (C-H insertion), C-N bond formation (intramolecular and intermolecular amination/amidation), C-F bond formation, and C-S bond formation.SCI(E)[email protected]
Photoinduced C—C Bond Cleavage and Oxidation of Cycloketoxime Esters
No full textA novel structural reorganization of cycloketoxime esters beyond the traditional Beckmann rearrangement process has been established to build cyano-containing ketones in the presence of photocatalyst. This novel transformation is remarkable with selective C—C bond cleavage and an oxidation process enabled by DMSO used as the solvent, oxidant, and oxygen source avoiding acid, base and toxic cyanide salts as the cyano source. Further applications in late-stage modification of complex and chiral molecules have also been reported

Harmonizing Biodiesel Fuel Standards in East Asia: Current Status, Challenges and Way Forward
No full textAbstract: This paper discusses the development of and policy towards biodiesel fuel (BDF) in the East Asia Summit (EAS) Region (hereafter East Asia), with a focus on activities related to harmonizing BDF standards. It finds that the EAS countries have actively promoted the development of BDF for a variety of reasons. To minimize problems with engines arising from the use of BDF, most EAS countries have established their national BDF standards. However, these diverse standards cause barriers for BDF trade and act against the regional interest in maximizing benefits from BDF production and utilization. Therefore, the EAS policy makers decided to harmonize BDF standards, and a regional benchmark standard has been published. Through a comparative review of existing national standards against the benchmark, it finds that the harmonization is beneficial economically and environmentally, and is technically feasible but practically stalled due to the lack of political determination. Therefore, among a few policy implications, the key message to deliver is a call for political determination to implement the harmonization in the EAS region. Since harmonization of BDF standards has been tried in other regions, the findings of this paper may supplement the literature, enhance understanding of the EAS case, and provide lessons and implications that may be helpful in advancing similar harmonization elsewhere.

The Shi arrangement and the Ish arrangement
No full textThis paper is about two arrangements of hyperplanes. The first — the Shi arrangement — was introduced by Jian-Yi Shi to describe the Kazhdan-Lusztig cells in the affine Weyl group of type A. The second — the Ish arrangement — was recently defined by the first author who used the two arrangements together to give a new interpretation of the q,t-Catalan numbers of Garsia and Haiman. In the present paper we will define a mysterious "combinatorial symmetry'' between the two arrangements and show that this symmetry preserves a great deal of information. For example, the Shi and Ish arrangements share the same characteristic polynomial, the same numbers of regions, bounded regions, dominant regions, regions with c "ceilings'' and d "degrees of freedom'', etc. Moreover, all of these results hold in the greater generality of "deleted'' Shi and Ish arrangements corresponding to an arbitrary subgraph of the complete graph. Our proofs are based on nice combinatorial labellings of Shi and Ish regions and a new set partition-valued statistic on these regions.Cet article traite de deux arrangements d'hyperplans. Le premier — arrangement Shi — a été introduit par Jian-Yi Shi pour décrire les cellules de Kazhdan-Lusztig du groupe de Weyl affine de type A. Le deuxième — arrangement Ish — a été récemment défini par le premier auteur pour donner une nouvelle interprétation des nombres q,t-Catalan de Garsia et Haiman. Ici nous définissons une mystérieuse "symétrie combinatoire" entre les deux arrangements et nous montrons que cette symétrie conserve un grand nombre d'informations. Par exemple, les arrangements Shi et Ish ont le même polynôme caractéristique, le même nombre de régions, de régions bornées, de régions dominantes, de régions avec c "plafonds'' et d "degrés de liberté'', etc. En outre, ces résultats se généralisent aux arrangements Shi et Ish "deleted'' correspondant à un sous-graphe arbitraire du graphe complet. Nos preuves reposent sur des étiquetages combinatoires des régions Shi et Ish, et sur une nouvelle statistique associée
