preponderance of regioisomeric sugar-derived tetrazoles (up to 75% total yield) obtained upon photolysis of protected (benzyl, acetyl) glucopyranosylidene diazides, even in the presence of added acrylonitrile, proved that azidonitrene intermediates predominate over anomeric carbenes, in the reaction. Revisions are presented for its mechanism and one structure.
