资源简介：
The
complex [W(CO)5{PClPh2}] reacts with AlCl3 to form a mixture of the phosphenium complex [W(CO)5{PPh2}][AlCl4] and an isocarbonyl, with GaCl3 to form [W(CO)5{PPh2}][GaCl4], and with silver trifluoromethanesulfonate to form [W(CO)5{P(OSO2CF3)Ph2}]. All three complexes
react as strong P electrophiles, undergoing electrophilic substitution
reactions with aromatic and heteroaromatic compounds, alkenes, and
alkynes, to form aromatic and heteroaromatic phosphines, allyl phosphines,
and alkynyl phosphines, respectively. Alkenes lacking cleavable γ-H
atoms and internal alkynes undergo tandem electrophilic addition/substitution
reactions, adding between the P and one of the phenyl rings to form
fused P heterocycles. The newly formed phosphines can be removed from
the tungsten complex by photolysis in the presence of bis(diphenylphosphino)ethane.
