Abstract

Abstract Flash vacuum pyrolysis of 1-(1?-adamantyl) acetylene [2-14 C](780) gives recovered alkyne which contains 25% of the rearranged product, 1-(1?-adamantyl) acetylene [1-14 C]. 1-Ethynyl-1-methylcyclohexane (740) is converted into toluene and benzene, while evidence for rearrangement of 3, 3-dimethylbut-1-yne [2-13 C](790) and 3- methyl-3-phenylbut-1-yne [2-13 C](680) was not obtained before the onset of alternative ...
