Abstract Phosphinic acids may be efficiently esterified in microwave-assisted reactions with alcohols. Especially alcohols with longer alkyl chain are suitable reagents for direct esterifications. At the same time, the directamidation cannot be complete under such conditions. Hence, the tradional amidations via the phosphinic chloride intermediates have to be applied.

Microwave-assisted, ionic liquid-catalyzed aminolysis and alcoholysis of phosphinic derivatives: the interconversion of phosphinates and phosphinic amides
was developed for the preparation of alkylamino-3-phospholene oxides and for the diastereoselective synthesis of alkylaminophospholane oxides by the MW-assisted ionic liquid-catalyzed aminolysis of the corresponding cyclic phosphinates. The opposite reaction, the alcoholysis of cyclic phosphinicamides, was also elaborated. The interconversion of phosphinates and phosphinicamides may be of more general
