摘要:
The current invention relates to the structure, synthesis of dialkyl(2,4,6- or 2,6-alkoxyphenyl)phosphine or its tetrafluoroborate, as well as its applications in the palladium catalyzed carbon-chlorine bond activation for Suzuki coupling reactions and carbon-nitrogen bond formation reactions. The dialkyl(2,4,6- or 2,6-alkoxyphenyl)phosphine or its tetrafluoroborate could coordinate with the palladium catalyst to activate the inert carbon-chlorine bond highly selectively and catalyze Suzuki coupling reaction with arylboronic acid or carbon-nitrogen bond formation reaction with organic amines. The current invention uses only one step to synthesize dialkyl(2,4,6- or 2,6-alkoxyphenyl)phosphine and its tetrafluoroborate is stable in the air. Compared with known synthetic routes of ligands used in activating carbon-chlorine bonds, the method of current invention is short, easy to operate. Moreover, with this type of ligands, the Suzuki coupling products of optically active chlorolactones and arylboronic acids would maintain their configuration and optical purity.
