1-Alkyl-1H-benzotriazoles react with dimethyldioxirane to give the corresponding 1-alkyl-1H-benzotriazole 3-oxides 712. In contrast, under similar conditions, 2-alkyl-2H-benzotriazoles 713 are converted into the corresponding trans-4,5,6,7-diepoxy-4,5,6,7-tetrahydro-2H-benzotriazoles 714 (Scheme 264).[‌715‌]
