Abstract The reaction of terminal phosphinidene complexes [RP–W(CO) 5 ] with vinylboronic acids is very sensitive to the presence or absence of solid K 3 PO 4 in suspension in the reaction medium. The products are phosphirane complexes without the salt and secondary vinylphosphine complexes in the presence of the salt. This shift of the reaction pathway is explained by the formation of vinyborates in the presence of potassium phosphate.
