Condensation of 2-aminophenol with boronate ester derivatives of benzaldehyde afforded the corresponding boron-containing Schiff bases, 2-HOC6H4N=C(H)C6H4R (1a: R = 2-Bpin; 1b: R = 3-Bpin; 1c: R = 4-Bpin; pin = 1,2-O2C2Me4). Crystals of 1b were triclinic, space group P, a = 11.9420(6), b = 13.0871(7), and c = 13.2720(7) A, α = 70.983(1), β = 67.793(1), and γ = 78.380(1)°, Z = 2. Reaction of 2-aminophenol with
2-氨基苯酚与苯甲醛的硼酸酯衍生物缩合得到相应的含硼席夫碱,2-HOC6H4N=C(H)C6H4R (1a: R = 2-Bpin; 1b: R = 3-Bpin; 1c: R = 4-Bpin;引脚 = 1,2-O2C2Me4)。1b 的晶体为三斜晶系,空间群 P,a = 11.9420(6), b = 13.0871(7), and c = 13.2720(7) A, α = 70.983(1), β = 67.793(1), and γ = 78.380(1)°,Z = 2。然而,2-氨基苯酚与 2-HC(O)C6H4B(OH)2 在 EtOH 中的反应得到具有 OBOBO 结构单元的大环二聚体 2。该二聚体的分子结构已通过 X 射线衍射研究证实。2 的晶体为单斜晶系,空间群 P21/c,a = 10.0447(8),b = 21.0894(15),c = 12.6214(9) A,β
