Evidence for a Strained Cyclic Allene in the Ring Closure Reaction of Enynylketenes
We show in this paper using HF and MP2 ab initio calculationsthat the ring closure of 5 generates an intermediate best describedas the closed-shell cyclic allene 6a, instead of the usually assumeddiradical nature reported in the literature. This intermediate thengives rise to the formation of 7. The...
