Abstract

Abstract Flash pyrolysis of 1, 1-diethynyl-2, 2, 2-trimethyldisilane (16) and triethynylsilane (18) led to the formation of two silylenes of the elemental composition C 4 H 2 Si, namely diethynylsilylene (10) and ethynylsilacyclopropenylidene (7), which were isolated in an argon matrix at 10 K. Both compounds could be photoconverted into another isomer, butadiynylsilylene (9). The identification of these reactive intermediates is based on the ...
