Two types of novel BF2 complexes are readily obtained by the reaction of BF3OEt with 3-(2-oxo-2-arylethylidene)-3,4-dihydro-1H-quinoxalin-2-ones or 3-(2-oxo-2-arylethylidene)-3,4-dihydrobenzo[1,4]oxazin-2-ones, respectively in refluxing acetic acid/toluene solvent mixture. The complexes are confirmed by elemental analysis, FT-IR, 1H, 13C, 11B, 19F NMR and one of them is executed its X-ray crystallographic
两种类型的新颖的BF 2个络合物容易由BF的反应获得3 OET与3-(2-氧代-2- arylethylidene)-3,4-二氢-1- ħ -喹喔啉-2-酮或3-(2-氧代-2-芳基亚乙基)-3,4-二氢苯并[1,4]恶嗪-2-酮分别在回流的乙酸/甲苯溶剂混合物中。通过元素分析,FT-IR,1 H,13 C,11 B,19 F NMR证实了该配合物,并对其中之一进行了X射线晶体学研究。这些配合物的出色的光物理性质由紫外可见吸收和荧光发射光谱法确定。
