Facile phosphorus-carbon bond formation using a tungsten-coordinated phosphirenyl cation

Reaction of K2[W(CO)5] with Cl2PN-i- Pr2 in the presence of diphenylacetylene leads to the tungsten aminophosphirene complex [W(CO)5{P(N-i-Pr2)C(Ph)C(Ph)}] (1), which can be converted to th

Stepwise building of polyphosphirene chains

No end in sight: the mono-, bi-, and triphosphirenes 2, 3, and 5, respectively, are prepared by a simple iterative method (see scheme; 1 = [Ph ≡ CPW(CO)5], 4 = [PhPW(CO)5]); these oligomers offer numerous possibilities in coordination chemistry and catalysis. They can serve to create numerous other classes of polyphosphine chains by ring opening or ring expansion of the phosphirene units.
