Hydrogen abstraction from activated methyl, methylene, and methine compounds with 4-methoxy-2,6-diphenylphenoxyl proved to be a useful approach for the synthesis of the corresponding ethers of 4-methoxy-2,6-diphenylphenol.With triple activated methine com

Reactions of substituted cyanoacetate anions 4 with S,S-dialkylsuccinimidosulfonium salts resulted generally in the formation of N-alkylthiomethylketenimines and α-alkylthiomethylesters.Coupling products were also obtained with anion 4d and only observed in the case of methyl phenylcyanoacetate anion 4b.The results were interpreted by the formation of instable ?-sulfurane intermediates.Homolytic cleavage of these intermediates gave radical pairs, then the coupling products.Heterolytic cleavage gave new sulfonium salts which rearranged via sulfonium ylides.
Reactions of Triphenylphosphine- and Trialkyl Phosphite-Silver Nitrate Complexes with Positive Halogen Compounds. Synthesis of α-Nitro Nitriles

, p. 4498 - 4501 (2007/10/02)
The reaction of α-bromo-α-cyano esters, α-bromo-α-cyano nitriles, and α-bromo-α-cyano imides with triphenylphosphine- or trialkyl phosphite-silver nitrate complexes leads to replacement of the positive bromine atom by a nitro group under mild conditions.I
REACTION DES COMPOSES A HALOGENE POSITIF AVEC LES COMPLEXES 1:1 NITRATE D'ARGENT-TRIPHENYLPHOSPHINE OU PHOSPHITE DE TRIMETHYLE
Ketari, Rachid,Foucaud, Andre
, p. 2237 - 2238 (2007/10/02)
The reaction of α-bromo α-cyanoesters, α-bromo α-cyanonitriles and α-bromo α-cyanoimides with silver nitrate-triphenylphosphine or trimethylphosphite complexes brings about replacement of positive halogen by a nitro group in mild conditions.
