General synthesis of alkyl phenyl selenides from organic halides mediated by zinc in aqueous medium

Organic halides of different structural types react with diphenyl diselenide and zinc dust in aqueous medium to give alkyl phenyl selenides. Benzylic and allylic bromides, α-bromoesters, acids and ketones and some primary alkyl iodides produce high yields even under acidic conditions. Less reactive halides need basic medium. The reaction proceeds equally well in the presence of various unprotected functional groups. Control experiments support a SH2 mechanism via alkyl radicals.

SELECTIVE ONE-POT SYNTHESIS OF ALLENYL PHENYL SELENIDE AND 1-(PHENYLSELENO)PROPYNE. ROLE OF SODIUM BENZENESELENOLATE AS A BASE IN DMF

The reaction of excess sodium benzeneselenolate with propargyl bromide in DMF-THF at room temperature produced allenyl phenyl selenide or 1-(phenylseleno)propyne selectively, depending only on the reaction time.
