a source of the electrophilic phenylselenyl group. This relatively stable compound was utilized for an efficient α-selenenylation reaction of aldehydes and ketones catalyzed by l -prolinamide under mild reaction conditions. The organocatalytic asymmetric α-selenenylation of an aldehyde was also studied and the reaction was found to proceed with high enantioselectivity (96% ee).
