Safe and Efficient Tetrazole Synthesis in a Continuous-Flow Microreactor
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 NaN3, yet nonetheless displays a broad substrate scope. The hazards associated with HN3 are essentially eliminated, shock‐sensitive...

description | 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 NaN3, yet nonetheless displays a broad substrate scope. The hazards associated with HN3 are essentially eliminated, shock‐sensitive metal azides such as Zn(N3)2 are avoided, and residual NaN3 is quenched in‐line with NaNO2. |
