Abstract

Abstract Previously unknown bis (alkoxyethynyl)-substituted silanes, germanes, and stannanes were synthesized. Pyrolysis of bis (ethoxyethynyl)-substituted silanes and germanes was studied. Depending on the reaction conditions (pyrolysis in a solvent or vacuum pyrolysis without a solvent), the process affects either one ethoxyethynyl group to give (ethoxyethynyl) silyl (-germyl) ketenes or both ethoxyethynyl groups, affording silyl- ...
