The preparation of a new aluminium reagent, dimethylaluminium methaneselenolate (Me2AlSeMe) is described.The reactivity of this aluminium reagent toward a variety of organic substrates has been studied.Me2AlSeMe will convert O-alkyl esters to selenoesters in high yield.These selenoesters function as extremely reactive acyl transfer agents and are converted to acids, esters, and amides on reaction with water, alcohols or amines in the presence of a selenophilic metal cation.The selenoesters will, moreover, acylate reactive arenes and heterocyclic compounds when cuprous triflate is employed as the selenophilic metal cation.This latter transformation constitutes a new transition metal promoted variant of the Friedel-Crafts acylation reaction.
UNUSUAL REACTIVITY OF SELENOBORANES TOWARDS EPOXIDES: NEW SELECTIVE ROUTES TO β-HYDROXYSELENIDES AND ALLYLALCOHOLS

Selenoboranes react with terminal, α, β- di- and trisubstituted epoxides to produce β-hydroxyselenides (or olefins) in the two first cases and allyl alcohols in the last one.A very high stereodescrimination has been observed for α,β-disubstituted epoxides: the cis epoxide being much more reactive.
