Abstract
Configuration of a series of ten 1-cyano, 1, 2-diphenyl-cyclopropanes generated by the action of diazomethane upon the corresponding trans α-cyanostilbenes was established using N.M.R, spectra. Comparison between experimental and calculated data made possible the assignation to all compounds of a configuration in which the proton at carbon-2 lies in the trans position relating to the cyano group at the carbon-1. According to this result and owing to the configuration of the parents α-cyanostilbenes, the decomposition of the Δ-1 pyrazoline, which is an intermediate in the reaction considered, takes place stereospecifically.
