Progress in synthesizing arylboronic acid and its ester;

Under ultrasonic radiation,four single substituted arylboronic acid were synthesized through the reaction of trisubstituted borate and halogenated hydrocarbon induced by iodine.

By screening different organic solvents, it was found that NiCl_2·6H_2O can catalyze the homocoupling of arylboronic acids using K_2CO_3 as the base in pyridine to produce symmetrical biaryls in good yield.

Three thyronamines were synthesized from tyramine via a copper-promoted O-arylation of arylboronic acids with phenols as a key step.

In recent years, much attention have been fixed on the reations of N-arylation with arylboronic acids, the introduction of arylboronic acids as reaction partners has been a significant improvement over previous methods.

This thesis deals with tuning the selectivity of Heck-type coupling vs conjugate addition (HC/CA) in rhodium-catalyzed reactions of arylboronic acids with a, β-unsaturated carbonyl compounds in toluene-H_2O, consisting of four parts:1.
