摘要

Abstract Flash pyrolyses of four suitable precursors–namely 1, 1, 1-trimethyl-2- propargyldisilane (32), its allenyl (34) and propynyl isomer (35), as well as 2-ethynyl-1, 1, 1, 2-tetramethyldisilane (31)–lead to the formation of three C 3 H 4 Si species (7, 11, and 15). By examination of their photochemistry five additional compounds of the same composition (12, 13, 14, 17, and 18) were identified. Except ethynylsilaethene (18), all compounds ...
