Cycloaddition reactions of diazoalkanes, with R = H and R' = H, alkyl, aryl or alkoxycarbonil, yield syn-adducts with dichlorocyclobutene.Diphenylnitrilimine, however, mainly undergoes anti-additions.Two phenomena not described as yet will be discussed for the interpretation: the influence of substituents in 3,4-position on the out-of-plane distortions of the olefinic hydrogen atoms and vicinal torsional interactions in model transition structures.
