Abstract

The reaction of bisgermavinylidene [(Me₃SiN=PPh₂)₂C=Ge→Ge=C(PPh ₂=NSiMe₃)₂] (1) with M(CO)₅(THF) (M = Cr, W, Mo) afforded the metallagermacyclopropane [(Me₃ SiN=PPh₂)₂CGeM(CO)₃{M(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)₃Mo{C(Ph₂P=NSiMe₃)₂}] (5); the X-ray structures of compounds 2 and 5 have been determined.
