Safe and Efficient Tetrazole Synthesis in a Continuous Flow Microreactor [PDF]

open access: yes, 2011
Safer flow: The synthesis of 5-substituted tetrazoles in flow (see scheme) is safe, efficient, scalable, requires no metal promoter, and uses a near-equimolar amount of NaN[subscript 3], yet nonetheless displays a broad substrate scope.
