  Facile Phosphorus–Carbon Bond Formation using a Tungsten-Coordinated Phosphirenyl Cation

  摘要：

  Reaction of K-2[W(CO)(5)] with Cl2PN-i-Pr-2 in the presence of diphenylacetylene leads to the tungsten aminophosphirene complex [W(CO)(5){P(N-i-Pr-2)C(Ph)C-(Ph)}] (1), which can be converted to the chlorophosphirene complex [W(CO)(5){P(Cl)C(Ph)C(Ph)}] (2) by reaction with HCl. Chloride abstraction from 2 with excess AlCl3 leads to the tungsten-complexed phosphirenyl cation [W(CO)(5){PC-(Ph)C(Ph)}][AlCl4] (3). Compound 3 reacts with PPh3 to form a phosphoniophosphirene complex and undergoes electrophilic aromatic substitution with ferrocene to form a ferrocenylphosphirene complex. Chloride abstraction from 2 with silver triflate leads to a phosphirenyl triflate complex, which reacts with PPh3 and ferrocene in the same fashion as 3 but also reacts cleanly with a wider range of substrates, including phenylacetylene and allyltrimethylsilane, to form respectively a phenyl-alkynylphosphirene complex and an allylphosphirene complex.
