The sulfenylation of ketones having alpha-hydrogens has been achieved using N-chlorosuccinimide (NCS) under mild reaction conditions to produce alpha-ketothioethers in excellent yields with high selectivity. The use of NCS makes this method quite simple, convenient and practical. (C) 2008 Published by Elsevier Ltd.

highly atom‐economical tandem Pd/Au‐catalyzed route to α‐sulfenylated carbonylcompounds from terminal propargylic alcohols and thiols has been developed. This one‐step procedure has a wide substrate scope with respect to substituents at the α‐position of the alcohol. Both aromatic and aliphatic thiols generated the α‐sulfenylated carbonyl products in good to excellent yields. A mechanism is proposed in

An in situ catalytic system was generated based on hydrazone-thioether ligands and Pd(OAc)2. It provided excellent catalytic activity in the Suzuki-Miyaura cross-coupling reactions between aryl halides and arylboronicacids in aqueous medium and under IR irradiation. The resulting coupled products were obtained in short reaction times, with low catalyst loads and in good to excellent yields. Density
