Article abstract of DOI:10.1039/DT9930003287

The compound (PPh3)3> 1 reacts with the Group 6 metal carbonyls, , in hot aromatic solvents giving different reaction products according to the stability of the metal carbonyl: (CO)4(PPh3)2> 2 (M = Cr); and trans- (M = W) and the dark brown 2(CO)6(PPh3)2> 3 (M = Mo).The structure of 3 has been established from X-ray diffraction analysis.This compound reacts, in boiling toluene, with diphosphines (Ph2P)2X to form 2(CO)4 (diphosphine)2> (diphosphine = dppm 4 or dppb 5) and for X = C2H4 (dppe) or C3H6 (dppp) a mixture of and (CO)(diphosphine)> was obtained.The new trinuclear complexes have been characterised by elemental analysis and by spectroscopic (IR and NMR) methods.
