Microwave irradiation accelerates some difficult Wittig reactions of stable phosphorus ylides (e.g. 1) with ketones. Irradiation in a domestic microwave oven of the mixture of reactants, in absence of solvents, allowed to obtain, in shorter times, an improvement of tranformation yields over conventional heating method.

Abstract
Microwave irradiation accelerates some difficult Wittig reactions of stable phosphorus ylides (e.g. 1) with ketones. Irradiation in a domestic microwave oven of the mixture of reactants, in absence of solvents, allowed to obtain, in shorter times, an improvement of tranformation yields over conventional heating method.File in questo prodotto:
