The permethylated catenated group 14 compound with the periodic chain C-Si-Ge-Sn is reported, 1a, together with the triphenyltin analog, 1b. Complete spectral characterization, including multinuclear NMR, is provided. The single-crystal structure of 1b is reported: the bond lengths Ct-Bu-Si, Si-Ge, and Ge-Sn, 1.900(9), 2.386(2), and 2.608(1) ?, respectively, are all in the normal range. Bond angle measurements indicate that the tert-butyl group dominates the structure resulting in significant distortions about the Ge atom. Photochemical treatment of 1a resulted in elimination of Me2Ge and Me2Sn, with a small amount of direct Ge-Sn cleavage. Treatment of 1a with n-butyllithium resulted in the predominant formation of Me3CSiMe2GeMe2Li and Me3Sn(n-Bu). Both the photochemical and n-BuLi reactions of 1a also produced (Me3CSiMe2GeMe2)2 as a significant byproduct.
