The synthesis and reactivity of [(HC=CCH2)(2,4,6-tBu3-C6H2O)]P=MoCP(CO)2 (3) is described. [(HC=CCH2)(R)]PCl (1) reacts with NaMoCp(CO)3 (2) to afford the sigma3,lambda4-phosphanediyl compound 3. With NEt3 a prototropic rearrangement of the 2-propynyl ligand of 3 to an allenyl group in [(H2C=C=CH)(R)]P=MOCP(CO)2 (5) is observed. However, with Cr(CO)5 .

Complex 7 contains a 1-phosphaallyl system, which is functionalized by an exocyclic CC double bond. X-ray structure analyses of 3 and 7 are performed. » weiterlesen» einklappen
