Synthesis, Structure and Spectroscopic Characteristics of 2'-Boryl-4''-dimethylaminochalcones. Effect of an Intramolecular Boron-Oxygen Coordinate Bond to the Conjugated System
摘要:
2'-Diethylboryl4 " -dimethylaminochalcone (1) and the related compounds (4)-(7) bearing a dioxyboryl group in the 2'-position were synthesized, and the effect of the intramolecular boron-oxygen coordinate bond on the spectroscopic characteristics of 4 " -dimethylaminochalcone chromophore was examined by comparison with 4 " -dimethylaminochalcone (2) using UV/NIS and fluorescence spectra.
