R and x* orbitals are strongly polarized in the same direction, as in styrene. The results also are discussed relative to earlier MNDO calculations. Recently we reported a detailed experimental and theoretical investigation of the stereoselectivity of alkylidenecarbene additions to o1efins.l Unsymmetrical alkylidenecarbenes R(CH,)C=C: (1-3) were found experimentally to add to two unsymmetrical olefins
