Synthesis and Fluorescence Properties of Thiazole–Boron Complexes Bearing a β-Ketoiminate Ligand
摘要:
Novel fluorescent dyes, thiazole boron complexes bearing beta-ketoiminate ligands, have been synthesized, and their fluorescence properties were investigated. The BF2 complexes showed a pronounced aggregation-induced emission enhancement effect because of the restriction of C-Ph intramolecular rotation. The BPh2 complexes showed higher fluorescence quantum yields than the corresponding BF2 complexes, both in solution and in the solid state.

α,β‐Unsaturated acyl ammoniums generated from the reaction of α,β‐unsaturated 2,4,6‐trichlorophenol (TCP) esters bearing a pendent enone with an isothiourea organocatalyst are versatile intermediates in a range of enantioselective nucleophile‐dependent domino processes to form complex products of diverse topology with excellent stereoselectivity. Use of either 1,3‐dicarbonyls, acyl benzothiazoles,
