WebbAzides have long been obtained exclusively via hydrazides since their first preparation by Curtius. Shioiri et al. (1972), however, devised an interesting alternative to the hydrazide-mediated azide method, and reported that diphenylphosphorylazide (DPPA, 9 in Fig. 4) directly converts a free carboxyl group to an azide (Shioiri and Yamada, 1974).The … Webb25 maj 2024 · Lead(II) azide is an initiating explosive; even a small amount can trigger an explosion caused by simple external stimuli, such as sparks, flames, friction or pinpricks, and is able to initiate the explosive reaction of rock-crushing explosives.
