Abstract:
Associated -phosphinodiborane, (-H2PB2H5)n, is formed in the reaction of H2P(BH3)2Na with HCl in diethyl ether solution at –96°C. The formation of B–H–B bridges is demonstrated by IR and11B-NMR spectra. (-H2PB2H5)n decomposes thermally to diborane and polymeric phosphinoborane analogous to -H2NB2H5. Other phosphorus substituted -phosphinodiboranes associated via B–H–B bridges are formed in the reaction of the salts (CH3)PH(BH3)2Li, (CH3)2P(BH3)2Li, andPhPH(BH3)2Li with HCl.Mit 6 AbbildungenHerrn Professor Dr.E.
