Hydrazoic acid, safe substitute for

Unlike hydrazoic acid, trimethylsilyl azide is thermally quite stable. Even at 200° it decomposes slowly and without explosive violence. Accordingly it is a very convenient and safe substitute for hydrazoic acid in many reactions. A notable example is the cycloaddition of hydrazoic acid to acetylenes which is a general route to substituted triazoles.4 The reaction of trimethylsilyl azide with acetylenes is also a general reaction from which the 2-trimethyIsilyI-1,2,3-triazoles may be obtained in good yield.5 On hydrolysis these adducts are converted under mild conditions to the parent alkyl 1,2,3-triazoles.5...
