Reactivity of Woollins' Reagent toward 2-En-1-imines (Schiff Bases): A Facile Approach to Synthesize New Selenium-Phosphorus-Nitrogen Heterocycles

摘要

Woollins' Reagent serves as a reductive cycloaddition reagent, reacting with 2-en-1-imines containing a conjugated C=C bond group (Schiff bases) leading to a series of four-, five-, six-membered 1,2-azaphospholidines incorporating one or two N-P=Se linkages. Ten single-crystal X-ray structures confirming the formation of these small N-P-Se heterocycles are reported.
