通过易得的芳酰肼与二硫化物的铜催化的氧化偶联,开发了另一种硫酯化反应,其中N 2的氧化排出克服了羧酸衍生物和产物之间的活化障碍。该反应以良好的收率和优异的官能度耐受性产生了各种硫酯。在该反应中,将稳定且容易获得的芳酰基酰肼用作酰基源,并将相对无味的二硫化物用作S源。机理研究表明,铜盐与氧化剂(NH 4)2 S 2 O 8的反应 可以实现串联过程,包括去质子化,自由基介导的脱氮和CS键形成。
During the acid-catalysedcyclisation of some o-arylthiophenyl-substituted carbinols to thioxanthen derivatives, arearrangement was observed with carbinols having a para-methyl substituentin thearylthio-group. Thus, 1-[o-(p-tolylthio)phenyl]ethanol gave 3,9-dimethylthioxanthen, while α-[o-(p-tolylthio)phenyl]benzyl alcohol gave a mixture of 3-methyl- and 2-methyl-9-phenylthioxanthen. The mechanism

A copper‐catalyzedthree‐component (arenes, iodohydrocarbon, and sulfur powder) synthesis of substituted aryl sulfides has been developed. Water is used as the green solvent in a simple and environmentally friendly procedure. Various functional groups attached to the substrates were well tolerated in this process to afford the corresponding products in moderate to good yields.

A new strategy for the design of inclusion compounds is described. The approach is based on the analogy between the hydrogen-bonded hexamer unit present in the clathrates of phenol, quinol, Dianin's compound, and other hydroxyaromatic hosts, and a hexasubstituted benzene. Suitable hexasubstituted benzenes have been prepared, and on recrystallisation from various solvents, a wide range of inclusion behaviour

Abstract Adducts of bis(diphenylphosphino)methane (dppm) with copper(I) thiolates can be prepared by oxidizing anodic copper into an acetonitrile solution of dppm and RSH (R = n-C4H9, C5H11, C6H5, o,m,p-CH3C6H4, 2-naphthyl). The products are (CuSR)2·dppm for R = n-C4H9, C5H11 or C6H5, and CuSR·1.5dppm for R = o-CH3C6H4 or 2-naphthyl. No adducts were obtained for R = m- or p-CH3C6H4. Reaction between
