Reactions between nitrile oxides and benzylic carbocations are described. Different results were obtained when the carbocations were generated from the corresponding chlorides with different Lewis acids, with addition products such as benzoxazines, oximes, and amides being produced. Primary, secondary, and tertiary carbocations showed different reactivities. The product ratios strongly depended on the substituents on the aromatic ring of the benzylic carbocations. Evidence for the proposed mechanism is reported. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
Stabilities of Carbonium Ions. IV. Steric Effects in the Solvolysis of Substituted Diphenylmethyl Chlorides

The replacement of ortho-hydrogen atoms by methyl groups in diphenylmethyl chloride has three distinguishable results upon the rate of solvolysis.Firstly, the alkyl group activates by its electronic effect; secondly, steric interactions diminish all obsse
