| Abstract: | The reaction of bisgermavinylidene (Me3SiN=PPh2)2C=Ge-->Ge=C(PPh2=NSiMe3)2] (1) with M(CO)5(THF) ( M = Cr, W, Mo) afforded the metallagermacyclopropane (Me-3SiN=PPh2)2CGeM(CO)3M(CO)5]] M = W (2), Cr (3), Mo (4)]; in one of the reactions, compound 4 reacts further to give a "pincer" carbene complex (CO)3MoC(Ph2P=NSi Me3)2]] (5); the X-ray structures of compounds 2 and 5 have been determined. |
