摘要

Qualitative theoretical consideration suggest that substitution of a heteroatom for a C atom in an alternant hydrocarbon might results in a non-Kekulé with a triplet ground state, despite the nondegeneracy of the Hückel MBMOs of the heteroatom derivatives. The syntheses of 3- methylene-1-phenoxyl and 3-methylene-1-naphthoxyl are described. These compounds. biradical valence tautomers of m-quinomethanes, are characterized by EPR spectroscopy ...
