Cyclodimerization of readily accessible acetylenic ketones facilitated by a phosphane–borane complex under basic conditions is achieved. This methodology allows one-pot synthesis of phosphorus-involved tetrasubstituted furans via the construction of a C–P bond and a furan ring within a single procedure. A plausible reaction mechanism is proposed.
