资源简介：
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 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 phenylalkynylphosphirene
complex and an allylphosphirene complex.
