Popis:	Treatment of tetrakis(trimethylstannyl)methane with one equivalent of methyllithium followed by one equivalent of Me 3 MCl gives mixtures of the type C(SnMe 3 ) n (MMe 3 ) 4- n (M = Si, Pb; n = 0−3), which have been characterised by multinuclear ( 13 C, 29 Si, 119 Sn, 207 Pb) NMR. The main component (ca. 40%) is in each case (Me 3 Sn) 3 CMMe 3 , but considerable amounts of the other tetrametallamethanes are also present.
