(Chemical Equation Presented) Really (di)radical: Calculations show that parent 2,4-diborata-1,3-diphosphoniocyclobutane-1,3-diyl I has a negligible singlet-triplet energy gap (1.2 kcal mol-1) and would be a perfect diradical that could undergo both disrotatory and conrotatory ring closures to give bicyclo[1.1.0]butane derivatives I′ and I″. The synthesis of a type I′ derivative is presented.
