Electrophilic terminal phosphinidene complexes [Ar-Ar-P-W(CO)5] (Ar-Ar: biaryl or an analogue thereof) undergo a spontaneous insertion of the phosphorus atom into the vicinal C-H bonds to give annelated phospholes. Twelve examples are described, including biphenyl, thienyl, pyrrolyl, and benzofuryl groups as biaryl moieties. The activation energy of the insertion reaction is quite low (about 2 kcal mol-1).

Dibromophosphines, RPBr2, are obtained by reaction of tetrabromomethane with 7-substituted 7-phosphanorbornenes in toluene at ca. 100 °C. The phosphanorbornenes are obtained in situ by cycloaddition of N-phenylmaleimide with 1-substituted 3,4-d
