An efficient desulfonylation method mediated by magnesium in ethanol

Abstract An extremely convenient desulfonylation method of primary, secondary, tertiary alkyl and vinyl phenyl sulfones was developed by using magnesium in ethanol in the presence of catalytic amount of mercuric chloride to give the corresponding alkanes and alkene in almost quantitative yields.

An efficient Julia olefination mediated by magnesium in ethanol

Abstract Reductive elimination step of Julia olefination was conveniently achieved by using magnesium powder in absolute ethanol in the presence of catalytic amount of mercuric chloride at room temperature to give the corresponding alkenes in almost quantitatively yields.

An efficient deoxygenation of 1-alkenyl or alkyl phenyl sulfoxides to the corresponding sulfides mediated by magnesium in alcohol

Abstract An extremely convenient deoxygenation of 1-alkenyl, alkyl, and aryl phenyl sulfoxides with magnesium powder in absolute methanol (or ethanol) afforded the corresponding sulfides in excellent yields.
