On treatment with an excess of sodium azide in the presence of titanium(IV) chloride in boiling acetonitrile, both aliphatic and aromatic ketones are smoothly converted to 1,5-disubstituted 1H-tetrazoles in high yields.

was found to be an efficient reagent for hydrochlorination of α , β -unsaturatedketones to afford the corresponding β -chloroketones in good yield at ambient temperature. Reactions of the titled compounds with TCS-NaN 3 as well as with nitriles utilizing TCS-ZnCl 2 to give 1,5-disubstituted tetrazole derivatives or β -amido ketones respectively are also described.
