The synthesis and antimicrobial profile of imidazoliumionicliquids containing selenium are described herein. Minimum inhibitory concentration revealed that these compounds are especially active against algae, and their activity is modulated by substituents attached to the selenium moiety as well as by the counterion.
Preparation of α-Arylseleno-substituted Zinc and Copper Organometallics and their Application in the Synthesis of α-Arylselenomethyl Ketones

日期:——
α-Arylseleno-substituted zinc and copper organometallics, prepared by zinc insertion into the carbon–chlorinebond of α-chloromethyl aryl selenides and with CuCN–2LiCl transmetallation to the corresponding copper reagents, react with acyl chlorides to give α-arylselenomethyl ketones based on the formation of a new carbon–carbon bond.
