Abstract

The interconvertibility of sila-olefins and silanediyls, exempli- fied by reactions (1) and (-l), is a question of some current interest and controversy. Pyrolysis of 1,l-dimethylsiletane' is a clean source of 2-methyl-2-silapropene (Me2Si=CH2) , which dimerizes to a 1,3-disiletane; 1-methylsiletane would likewise be expected to be a source of 2-silapropene, but its pyrolysis, alone and with butadiene and trimethylsilane as trapping agents at 925 K, gave clear evidence for ...
