    • - obtained by reduction of the corresponding stable carbene IIa. According to ESR spectroscopy and ab initio calculations, the additional electron is not located at the carbene carbon atom but delocalized into the PhCN fragment: Enders, D.; Breuer, K.; Raabe, G.; Simonet, J.; Ghanimi, A.; Stegmann, H.

    • The stereochemical results are most compatible with concerted addition of 1a to styrene, in accord with typical singlet carbene behavior, and with the lack of theoretical prohibition of concerted nucleophilic carbene-olefin [1+2] cycloadditions. However, there is no spin-inversion barrier to rapid closure of a 1,3-dipole, so that a two-step singlet carbene addition is not as certain to occur nonstereospecifically as in a triplet carbene addition, which proceeds via a triplet 1,3-diradical.
