N-alkylation of amines by the reaction with xanthate esters in the presence of acetic acid catalyst in ethanol is reported. Short reaction time, high yield, general applicability and environmentally benign nature are the noteworthy features of our protocol. The probable mechanism for the formation N-alkylation of amines is proposed.

supporting information; experimental part, p. 1731 - 1734 (2011/09/16)
Using NaH as the base and DMSO as the solvent, a series of symmetric (E)-stilbenes were prepared in good yields via the -homocoupling of 1,3-dibenzylbenzotriazolium bromides at room temperature. Georg Thieme Verlag Stuttgart · New York.
Nucleophilic substitution of benzotriazolylalkyl chlorides with Grignard reagents: A direct route to benzotriazoloalkyl(hetero)aromatic compounds
Katritzky, Alan R.,Abdel-Fattah, Ashraf A. A.,Tymoshenko, Dmytro O.,Belyakov, Sergei A.

Benzotriazolylalkyl chlorides 5 react with (hetero)aromatic Grignard reagents generated from the corresponding halogen derivatives to afford benzotriazoloalkyl(hetero)aromatic compounds 8a-k and 10a-c in good yields.
Oxidation of 1-[(Aryl)(phenylseleno)methyl]-, 1-[(Aryl)(arylthio)-(phenylseleno)methyl]-, and 1-[(Aryl)(diphenylseleno)-methyl]benzotriazoles with m-Chloroperbenzoic Acid

During the last decade, benzotriazole (1) has received much attention as an excellent synthetic auxiliary [1]. Recently Katritzky, et al. [2] studied the oxidation of 1-(phenylthiomethyl)benzotriazole (2a) and 1-(2-phenyl-1-phenylthioethyl)benzotriazole (2b) and obtained their sulfones and sulfoxides by treatment with m-chloroperbenzoic acid (m-CPBA) and sodium periodate, respectively. No compounds derived from a heterolytic cleavage between the α-carbon and the N-1 atoms of the foregoing compounds were isolated.
