A 1,4-di(2,6-diisopropylphenyl)-1,2,3-triazol-5-ylidene (tzIPr)-based PEPPSI-typepalladiumcomplex was developed as an excellent precatalyst for the Suzuki–Miyauracross-couplingreaction. The complex showed high activity under mild conditions for the cross-couplingreactions between various types of aryl chlorides and aryl boronic acids regardless of the steric and electronic nature of the substrates

The Negishi cross-coupling of arylzinc reagents with various bromoanilines is accelerated by the presence of i-Prl (1 equiv) and furnished the expected biaryls within 5-12 min reaction time at 25 degrees C. Arylzinc reagents can also be cross-coupled under these conditions with a range of aryl bromides bearing an enolizable ester or acidic benzylic protons.
