Alkali metal salts of 1,2,3-benzodiazaborines: Platforms for late-stage N-functionalization and metal complexation
The standard procedure for the preparation of benzoid 1,2,3-diazaborines (DABs) is the condensation of 2-formylphenyl boronic acid with a hydrazine. The choice of hydrazine derivative irreversibly predetermines the N-substituent in…
