PHOSPHOLE SULFIDES AS 6-ELECTRON η4-c4, η1-S CHELATING LIGANDS
摘要:
The reaction of 1-phenyl-3,4-dimethylphosphole sulfide with [M(CO)(3)] sources (M=Cr, Mo) yields the corresponding eta(4)-C-4, eta(1)-S-M(CO)(3) complexes. The X-ray crystal structure analysis of the Cr-complex reveals an original type of complexation of the P=S unit which lies half-way between a eta(1)-S and a eta(2)-P=S bonding mode.
