Synthesis of new amino phosphonates based on secondary amines using microwave activation and phthalocyanine catalysis.

The condensation of diethyl phosphite with aldehydes and cyclic ketones under conditions of thermal catalysis and microwave radiation (MW) afforded new amino phosphonates based on secondary amines, including those containing gem-dichlorocyclopropane and cyclic acetal fragments. The optimization of conditions for obtaining the target products using MW radiation showed that dialkylamines are more active than the secondary amines used. [ABSTRACT FROM AUTHOR]
