Synthesis, characterization and thermolysis of phosphinite–borane adducts: investigation of an unusual thermally-induced phenolelimination reaction
Abstract
The synthesis, characterization and thermolytic behavior of a new class of phosphinite–borane adducts containing the bulky 2,4,6-t-Bu3C6H2O (Mes*O) group is reported, including the description of the first example of a primary phosphinite–borane adduct isolable at room temperature (Mes*O)PH2·BH31. Adduct 1 and the phenylated derivative (Mes*O)PhPH·BH33 formed highly cross-linked solids, 7 and 8, when heated to 100 and 140 °C, respectively. Characterization of these solids by solid state and
