A Highly Modular One-Pot Multicomponent Approach to Functionalized Benzobphosphole Derivatives

摘要

Benzofbjphosphole derivatives have attracted significant attention for their unique optoelectronic properties with potential for application in materials science. Herein we report a modular approach to a benzobphosphole derivative based on a one-pot sequential coupling of an arylzinc reagent, an alkyne, dichlorophenylphosphine (or phosphorus trichloride and a Grignard reagent), and an oxidant (for example H2O2, S, or Se). The approach allows for the construction of a library of previously inaccessible, structurally diverse benzofbjphosphole derivatives with unprecedented ease.
