The investigation of the Schmidt reaction with different classes of compounds2-6 under varying conditions has led to a better understanding of the factors involved in the rearrangement. Since the Schmidt reaction with olefins carried out by Mc-Ewen and co- workers4 and Kuhn and Di Domenico'leads to relatively large amounts of by-product through the polymerization of I, 1-diphenylethylene to 3--methyl-l, 1, 3-triphenylindane, 4a ...
