K2S2O8-promoted C-Se bond formation to construct α-phenylseleno carbonyl compounds and α,β-unsaturated carbonyl compounds

A novel K2S2O8-promoted C-Se bond formation from cross-coupling under neutral conditions has been developed. A variety of aldehydes and ketones react well using K2S2O8 as the oxidant in the absence of catalyst and afford desired products in moderate to excellent yields. This protocol provides a very simple route for the synthesis of α-phenylseleno carbonyl compounds and α,β-unsaturated carbonyl compounds.

N, N, N -Triphenylselenylisocyanuric Acid (TPSCA): A New Versatile Reagent for α-Phenylselenenylation of Aldehydes and Ketones

A new, versatile reagent, N,N,N-triphenylselenyl-isocyanuric acid (TPSCA) has been prepared, characterized, and used as a source of the electrophilic phenylselenyl group. This relatively stable compound was utilized for an efficient α-selenenylation react
