α-Organylchalcogenation of aldehydes and ketones with diorganyl dichalcogenides promoted by K3PO4
摘要:
A new catalytic method for direct alpha-organylchalcogenation of aldehydes and ketones has been developed. When various aldehydes and ketones were allowed to react with diorganyl dichalcogenides in the presence of K3PO4, under mild reaction conditions, the corresponding alpha-organylseleno and alpha-arylthio aldehydes and ketones were obtained in good to high yields.
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.
