Article abstract of DOI:10.1016/0022-328X(94)24763-9

Tris(2,6-dimethoxyphenyl)borane, Φ3B (Φ = 2,6-(MeO)2C6H3), an air-stable crystalline compound, formed isolable 1:1 adducts with ammonia and some primary amines but not with tertiary amines, secondary amines, or sec-alkylamines.Some tetraalkylammonium tris(2,6-dimethoxyphenyl)cyanoborates <Φ3B-CN> are soluble both in water and in benzene, and the stearyltrimethylammonium salt is soluble even in n-hexane.The freezing point depression measurements for some tetraalkylammonium salts suggested that they are associated in benzene by several molecules.Keywords: Boron; 2,6-dimethoxyphenyl; Borate; Amine; Phosphonium; Solubility
