A series of organotin(IV) complexes have been synthesized by reacting potassium o-isobutyl carbonodithioate with di- and triorganotin halides in methanol under stirring conditions. The newly synthesized complexes have been characterized by elemental analysis, FT-IR, NMR (1H and 13C) and X-ray crystallography. The FT-IR results show that the ligand acts as bidentate in complexes 1–3 and monodentate

We present a simple, easily scalable route to monodisperse copper sulfide nanocrystals by the hot injection of a series of novelcopper(I) xanthate single-source precursors [(PPh3)2Cu(S2COR)] (R = isobutyl, 2-methoxyethyl, 2-ethoxyethyl, 1-methoxy-2-propyl, 3-methoxy-1-butyl, and 3-methoxy-3-methyl-1-butyl), whose crystal structures are also reported. We show that the width of the obtained rods is

A novel and efficient oxidative esterification for the selectivesynthesis of α-ketoesters and esters has been developed under metal-free conditions. In the protocol, various α-ketoesters and esters are available in high yields from commercially available ketones and potassium xanthates. Mechanistic studies have proven that potassium xanthate not only promotes oxidative esterification but also provides
