New General One-Pot Synthesis of 1-Alkoxy Cyclic Phosphine Derivatives

Abstract

Treatment, at room temperature, of benzothiadiphosphole 1 with bis-Grignard 2, sodium alcoholate and finally with S₈ afforded 1-alkoxy cyclic phosphine sulfides in good yields. In a similar manner, reactions with sodium phenylthiolate gave the corresponding 1-phenylsulfanyl cyclic phosphine derivatives.

Key words

phosphorus - heterocycles - Grignard reactions - cyclizations - 1-alkoxy cyclic phosphine sulfides
