Reactive intermediates. Part XIX. The lithium salt of 1-(benzotriazol-1-yl)-4-p-tolylsulphonyltetrazene: a new benzyne precursor
Abstract
The lithium salt obtained from the monoanion of 1-aminobenzotriazole and toluene-p-sulphonyl azide is isolable, but gives benzyne immediately when dissolved in tetrahydrofuran or acetonitrile.
