The 1,3-diphenyl-2-azaallyl anion adds almost quanti- tatively to 2-phenylpropene with retention of the con- formation of the anion. Two racemic diastereoiso- meric [3+2] cycloadducts, i.e. the corresponding pyrro- lidines, are formed, in which both phenyl sub- stituents derived from the anion are cis oriented. The structures of racemic 3-methyl-r-2,c-3,c-5-triphenyl- pyrrolidine, C23H23N, (I), and 3-methyl-r-2,t-3,c-5-tri- phenylpyrrolidine, C23H23N, (II), were determined by X-ray analysis. There is no intermolecular hydrogen bonding in either crysta
