摘要

Four new phosphinoborane compounds were prepared and characterized by'H, 13C, 31P, and llB NMR spectroscopy and elemental analysis. Monomeric EtzBP (t-Bu) z was isolated as a volatile yellow liquid and [Me2BP (t-Bu) 2] 2 as a colorless solid using salt elimination reactions. The colorless dimeric solids [MezBP (SiMe3) zI2 and [Et~ BP (SiMe3) 2] 2 were prepared via trimethylsilyl halide elimination reactions. The dimeric compounds dissociate ...
