The Jacobseii rearrangement of 6-methyl-7-propyltetralin was initially investigated by Smith and Lo2 who reported that a low yield (25%) of 6-methyl-5-propyltetralin was obtained. This result quite apparently was a surprise to the authors since they commented at some length on the mode of formation of this product. Clearly this is a result of considerable mechanistic implication. The starting material contains four alkyl substituents on the benzene ring ...
