Über die‐Synthese und Molekülstruktur von CH3M(SiH3)3 (MSi, Ge)

Synthesis and Molecular Structure of CH3M(SiH3)3 (MSi, Ge) A solution of 2-isotetrasilanylsodium (1a) was obtained in good yield from silane and sodium under special conditions. Methylation of 1a with methyl p1-toluenesulfonate yields 2-methylisotetrasilane (1b). The corresponding methyltrisilylgermane (2b) was synthesized via (K, Cs)Ge(SiH3)3 (2a) resulting from the reaction of cesium trichlorogermanide with KSiH3 followed by methylation. The molecular structures of 1a and 1b were determined by electron diffraction analyses.
