Herein, we report the preparation and use of m-carboxybenzenesulfonyl azide as a diazo transfer reagent. This compound is an inexpensive and potentially scalable alternative to many of the diazo transfer reagents currently available, most of which ha

Heat and shock sensitive tosyl azide was generated and used on demand in a telescoped diazo transfer process. Small quantities of tosyl azide were accessed in a 'one pot' batch procedure using shelf stable, readily available reagents. For large scale
