Abstract

Various branched alkylcarbenes have been generated by alkaline decomposition of the corresponding tosylhydrazones. The intramolecular insertion reactions of these carbenes (formation of cyclopropanes) proceed with appreciable discrimination which depends strongly on steric effects. The product ratios are consistently explained by a transition state with approximately planar (eclipsed) configuration of the carbene-carbon and the carbon- ...
