Abstract
Aminoboranes and borazines having electronegative substituents (Cl) at boron yield crystalline adducts with bases such as pyridine. Steric effects in the base are important with regard to complex stability (pyridine complexes are more stable than those of α-picoline, which in turn are more stable than 2,6-lutidine complexes). Structural effects in the Lewis acid may determine stoicheiometry. Thus, in the series R2NBCl2/py, complexes of 1 : 1 (R = Pri), 1 : 2 (R = Me), and 1 : 3 (R = Et) stoicheiometry are found. These are believed to be R2N(Cl2)[graphic omitted]C5H5, [(R2N)CIB py2]+Cl–, and [(R2N)B py3]-+2Cl–, respectively.Keywords
