Small Rings, 34. Attempts to Synthesize Dimethyltetrahedrane

Irradiation of dimethyltricyclo2,5>pentanone (2) and 4,6-dimethyl-α-pyrone (6) in solution leads to products which are derivatives of 1,3-dimethylcyclobutadiene (1).However, in an argon matrix photochemical excitation of 2 results in the formation of methylenecyclobutene 12 which is in a photoequilibrium with vinylallene 11.Under analogous conditions pyrone 6 yields photostable 1,3-dimethylcyclobutadiene (1) via the bicyclic form 9.It is possible that dimethyltetrahedrane (14) is an intermediate in the decarbonylation of 2 into 11 12.
