WebThis complex comprises hydride, boryl, σ-borane, and dihydroborate ligands and is an active catalyst for the 1,4-hydroboration of N-heteroaromatics. A protocol has been developed such that the simple, air-stable alklyammonium complexes [NR 4 ] [ReO 4] can be exploited as pre-catalysts for hydroboration reactions. http://www.dspace.uce.edu.ec/bitstream/25000/17534/1/2024%20BORON%20TRIFLUORIDE%20ETHERATE%20IN%20ORGANIC%20SYNTHESIS.pdf
