Aryliminodimagnesium Reagents. XII. The Distribution of Products in the Condensation with Nitrobenzothiazoles. Reduction of Electron-Donating Ability of Reagent by the Interaction with Thiazolyl Group

The 4-, 5-, 6-, and 7-nitro derivatives of benzothiazole condense with ArN(MgBr)2 giving unsym-azoxy and -azo products.The product distribution indicated the mild nature of the reaction, and could be explained in terms of a reduced electron-donating ability of the reagent due to an interaction with thiazolyl group.
