| Abstract: | An in
situ generated catalytic system derived from PdCl2 and (C6H5)3CNH2
shows good-to-excellent activity (upto 92% isolated yield) in the microwave-assisted
Suzuki-Miyaura cross-coupling reactions of aryl halides with arylboronic acids
in aqueous media. Both electron-donating and electron-withdrawing aryl bromides
can be efficiently coupled with arylboronic acids. Chloroarenes can also be coupled,
but much lower yields are obtained. Interestingly, the same catalytic system is
also found to be effective for homocoupling reactions of arylboronic acids in
water. Moderate-to-excellent yields of symmetrical biphenyl compounds can be
achieved at room temperature. |
