Abstract:

A highly efficient Ullmann homocoupling reaction of aryl halides using palladium (II) phosphine-ylide complexes as homogenous pre-catalysts under aerobic conditions has been developed without the need for any chemical co‐reducing agents. The procedure is relatively mild and appears to have broad applicability, being useful for the homocoupling of both electron-deficient and electron-rich aryl halides and also homocoupling of phenylboronic acid and phenylacetylene.

Application of dimeric and monomeric ortho-palladated complexes as an efficient catalysts for Heck cross-coupling reaction

The catalytic acvtivity of dimeric and monomeric ortho-palladated complexes [Pd{C6H2(CH2NH2-(OMe)2,3,4}(µ-Cl)]2)2) and [Pd{C6H2(CH2NH2-(OMe)2,3,4}Cl(PPh3)](3), was investigated in Heck cross-coupling reaction. These complexes are more active and efficient catalysts for Heck cross-coupling reaction. The palladium complexes 2 and 3 is employed in the Heck cross-coupling reaction between styrene a...

Homocoupling of aryl halides in flow: Space integration of lithiation and FeCl3 promoted homocoupling

The use of FeCl(3) resulted in a fast homocoupling of aryllithiums, and this enabled its integration with the halogen-lithium exchange reaction of aryl halides in a flow microreactor. This system allows the homocoupling of two aryl halides bearing electrophilic functional groups, such as CN and NO(2), in under a minute.
