The preparation of a new aluminum reagent, dmiethylaluminum methaneselenolate (Me2AlSeMe) is described. The reactivity of this aluminum 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

Ultrasound-promoted desulfonylation of 5-substituted 4-tosyloxazoles, prepared from tosylmethyl isocyanide and carboxylic acid chlorides or by dianion chemistry, leads to 5-monosubstituted oxazoles.
