In order to avoid handling explosive sodium azide, some modifications of the normal procedure have been developed. One such modification involves the reaction of alkanoyl chlorides with the stable and nonhazardous trimethylsilyl azide. The alkanoyl azides thus formed undergo thermal degradation under relatively mild conditions and afford the corresponding isocyanates in high yields (‌Scheme 98‌).[‌448‌]
