摘要

Benzyl azide reacts with aryl isothiocyanates at 60" C to produce five types of products (5-9). The asymmetric bis adducts of type 6, formed as major components in the early stage of the reactions, rearrange into the more stable symmetrisc bis adducts 7 under a variety of conditions. Some derivatives of 6 also undergo partial or complete de-composition into the corresponding benzthiazole 15 upon treatment with Dabco. A precursor of the bis adducts, ...
