(Figure Presented) Remarkably stable 2-phosphabicyclo-[1.1.0]butanes (see picture; O red, P violet, W turquoise) were synthesized from the complexed phosphinidene Ph-P=W(CO)5 and cyclopropenes. These compounds undergo valence isomerization to form 3-phosphacyclobutenes via 1-phosphabutadienes at elevated temperatures.
