First Example of Alkylation of Secondary Phosphine Selenides

摘要

The secondary phosphine selenides I that recently has become available [1] are promising synthons for the synthesis of various organophosphorus-selenium compounds [2-7]. For example, their alkylation may result in derivatives of three- or four-coordinated phosphorus since they, similar to the corresponding phosphine oxides [8-10] and phosphine sulfides [10-12], might exist in the two tautomeric forms A and B.
