The complex (DMPP)Fe2(CO)7 in which DMPP (1-phenyl-3,4-dimethylphosphole) is η4-coordinated with Fe(CO)3 through its diene and η1-coordinated with Fe(CO)4 through its phosphorus atom is selectively decomplexed at phosphorus to give (DMPP)Fe(CO)3 by reaction with AlCl3 followed by NH4OH.This new η4-complex (DMPP)Fe(CO)3 can be oxidized, sulfurized and quaternized at phosphorus by H2O2, S8, and PhCH2Br and MeI, respectively,as an ordinary phosphine without decomplexation of the diene.As a free phosphole, this complex also gives a ring-expanded product by reaction with bezoyl chloride, water and Et3N.In the presence of some metallic salts such as (PhCN)2PdCl2, it loses CO to give the bimetallic sandwich 2.It can also give some new bimetallic complexes such as W(CO)5 by complexation of the phosphorus lone pair by W(CO)5(THF).
