from CH acids. All compounds were substituted with dialkylamino groups (NR2). The lone electron pair of the nitrogen atom of this donor moiety is variably delocalized toward the difluoroborate core that acts as the electron acceptor. This was rationalized in light of the various geometries of the amino group. The degree of charge transfer was quantified on the basis of the results of time-dependent density
由CH酸合成一系列二氟硼酸盐。所有化合物均被二烷基氨基基团(NR 2)取代。该供体部分的氮原子的孤电子对可变地偏向充当电子受体的二氟硼酸酯核。考虑到氨基的各种几何形状,这是合理的。基于随时间变化的密度泛函理论计算的结果来量化电荷转移的程度。
