The photochemistry of 1, 3, 3-trimethylcyclopropene and 1-tert-butyl-3, 3- dimethylcyclopropene has been investigated in hydrocarbon, methanol, and 1-hexene solution with far-ultraviolet (185-228 nm) light. Direct photolysis of the two compounds affords allene, alkyne, and 1, 3-diene derivatives, formally as a result of initial bond cleavage to yield vinylcarbene intermediates. Products derived from cleavage of the most ...
