Phosphine–borane derivatives. Part III. A proton magnetic resonance spectroscopic study of methyl- and silyl-phosphine with [1H6]- and [2H6]-diborane
Abstract
The 1H n.m.r. spectra indicate that hydrogen–deuterium exchange occurs between silicon and boron sites in silylphosphine–borane but not between carbon and boron sites in methylphosphine–borane. Condensation of monosilylphosphine to trisilylphosphine can be catalysed by diborane.
