Aliphatic ketones and aromatic carbonylcompounds on reaction with methylselenol and a Lewisacid, are shown to undergo acetalisation and/or reduction to methyl selenide, the unexpected reduction reaction being predominant in most cases.

The title transformation is efficiently achieved by using the selenium methodology which involves the sequential reductive alkylation of arylselenoacetals and of benzylselenides.

Alkyl aryl selenides react with lithium arenides to produce, regioselectively, alkyllithiums and lithium arylselenolates. Experimental conditions, especially the temperature, have a profound effect on the course of this reaction and on the nature of the products.
