Abstract

New substituted derivatives of the octahydrotriborate anion [B3H6Nu] with carboxylic acids were synthesized, where the nucleophile (Nu) is 1-naphthoic acid, 2-naphthoic acid, [1,1'-biphenyl]-4-carboxylic acid, 4-propylbenzoic acid, and decanoic acid. A targeted synthetic method for obtaining substituted derivatives with aminocarboxylic acids was developed. 11B NMR spectroscopy revealed that the derivative substituted with aminobenzoic acid undergoes a rearrangement, transforming from an amine-substituted to a carboxylate-substituted product.
