摘要：
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.
