Abstract
The acylation of Se-nucleophiles with N-acylbenzotriazoles was investigated. Samarium phenylselenolate and benzylselenolate (RSeSmI2) reacted with N-aroyl and N-alkanoylbenzotriazoles smoothly and afforded the corresponding selenol esters in good yields. Treatment of the RSeSmI2 with α,β-unsaturated N-acylbenzotriazoles afforded the anticipated α,β-unsaturated selenol esters in moderate yields, due mainly to the side reaction of conjugate addition.
