Abstract

Dimethylphenylborane has been prepared from BMe2Cl and HgPh2, and its vapour pressure measured over a range of temperature. The 1H n.m.r. band-shape method has been used to determine exchange parameters for the systems PMe2Ph·BMe3, PMe2(NMe2)·BMe3, PMe3·BMe2Ph, and PMe2But·BMe3. Reactions between complex and an excess of either donor or acceptor proceed by a dissociative mechanism. In dichloromethane at 27 °C, basicities towards BMe3 decrease in the order NMe3∼ PMe3 > PMe2But∼ PMe2(NMe2) > PMe2Ph [double greater-than, compressed] P(CH2Ph)3 > PMe2(CF3)∼ PMe3O ∼ PMePh2.
