Borane adducts of the water soluble phosphine PTA (PTA=1,3,5-triaza-7-phosphaadamantane) / S. Bolaño, A. Albinati, J. Bravo, L. Gonsalvi, M. Peruzzini. - In: INORGANIC CHEMISTRY COMMUNICATIONS. - ISSN 1387-7003. - 9:4(2006), pp. 360-363.
Abstract:
Boronation of the water soluble phosphine PTA (PTA= 1,3,5-triaza-7-phosphaadamantane) in dry THF easily affords the N-boronated adduct N-B-PTABH(3) which represents the first N-coordinated adduct of this popular water soluble phosphine (N-B-PTABH3= 1-boranyl-1,3,5-triaza-7-phosphadamantane). In situ P-31 NMR spectroscopy suggests the Occurrence of a stepwise boronation resulting in the addition of as many as four equivalents of BH3 to PTA to give the polyboranyl species N-x, P-y-B-PTA(BH3)((x+y)) (x= 1-3, y= 0,1). Hydrolysis of the monoboranyl adduct occurs slowly in the presence of water yielding back PTA and boric acid, H3BO3. (c) 2006 Elsevier B.V. All rights reserved.
