2-甲酰基苯硼酸和 1,1-二甲基肼缩合得到标题化合物,双(8-B-4)–1,3,5-三{2-[(N,N-二甲基亚肼基)甲基]苯基)}环硼氧烷,C27H33B3N6O3,预期的简单苯甲醛腙的三脱氢环状三聚体,也是第一个被发现具有两个结构的三苯基环硼氧烷衍生物。 B 螯合相互作用。双螯合引起分子不对称,但仅对中心硼氧霉素环产生轻微的褶皱。
Condensation of 2-formylbenzeneboronic acid and 1,1-dimethylhydrazine afforded the title compound, bis(8-B-4)–1,3,5-tris{2-[(N,N-dimethylhydrazono)methyl]phenyl)}boroxin, C27H33B3N6O3, a tridehydro cyclic trimer of the expected simple benzaldehyde hydrazone and the first triphenylboroxin derivative found to possess two B chelating interactions. The double chelation induces molecular asymmetry but effects only a slight puckering in the central boroxin ring.
