  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).

  experimental conditions for the preparation of trimethylsilyl enol ethers 3 from α-phenylseleno aldehydes 1, compatible with a limited deselenenylation of the substrate, were studied. Starling from α-phenylseleno ketones 2, the enoxysilanes 4, bearing a vinylic PhSe group, are the major products when triethylamine is the base. Trimethylsilyl enol ethers 5 with an allylic PhSe group arc also formed beside 4
