Abstract
Nitrobenzothiazoles react with Grignard reagents giving alkyl-nitroso-compounds, except the 4-nitro-isomer which affords alkyl-nitro-derivatives. The observed highly regiospecific alkylation can be interpreted in terms of the stability of a cyclohexadiene-type intermediate. Detailed mass spectra of the products are reported.Keywords
