A series of thienyl-substituted phosphirene P-W(CO)5 complexes were synthesized by reaction of the transient terminal phosphinidene complex [Ph-P-W(CO)5] with the appropriate thienyl-substituted alkynes. The X-ray structural study of these complexes shows coplanar thiophene and phosphirene rings, suggesting a good inter-ring conjugation. A combined 13C NMR-NBO analysis indicates that the C=C double bond of the phosphirene ring is highly polarizable. UV spectra show a red-shift of the absorption when converting the alkynes into the phosphirenes. CV data are also given.
