摘要: Abstract A one pot reaction of [M(CO)4L2] (M = Mo, L2 = 2,2′-bipyridine, 1,10-phenanthroline; M = W, L2 = 2,9-dimethyl-1,10-phenanthroline) with 1,4-dichloro-2-butyne and Ph4PCl was examined in chlorinated solvents over the range 40–129 °C. Production either [MCl(CO)2(η3-CH2C(COCl)C CH2)L2] (4) or [MCl2(CO)(η2-ClCH2C CCH2Cl)L2] found to be dependent upon solvent temperature, these reactions were insensitive presence water. Under controlled conditions, carried out alcohols, amines thiols gave related ester, amide thioester substituted η3-butadienyl complexes good yield. The structure propargyl complex confirmed by X-ray analysis.
