Abstract

Trimethylsilyl azide (TMSA) reacted with aryl isocyanates to give arylcarbamoyl azides, l-aryl- 5 (4H)-tetrazolinones, and/or l-aryl-4-(arylcarbamoyl)-5 (4H)-tetrazolinones, whose yields were dependent on the reaction conditione. The reaction between TMSA and benzoyl or thiobenzoyl isocyanates provides a facile method for the preparation of 5-aryl-3-hydroxy-l, 2, 4-oxadiazoles or-1, 2, 4-thiadiazoles, respectively. However, with phenyl or benzoyl ...
