摘要:
Tris(2,6-dimethoxyphenyl)borane, Phi(3)B (Phi = 2,6-(MeO)(2)C6H3), 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 [R,N][Phi(3)B-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.
