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...

• New bicyclic (alkyl)(amino)carbene (BICAAC) precursor compounds have been prepared ( 5b–d ). Using BICAAC carbenes, five new Pd-PEPPSI complexes 6a–e ) synthetized. The reported characterized by NMR, HRMS and XRD techniques. palladium 6ae shown high activity in Mizoroki–Heck coupling reaction even at as low 100 ppm loading. A series of alkylamino carbenes (where N -aryl = dipp, mes, 2,6-dimet...

The phenanthroline unit in an imine-based covalent organic framework (Phen-COF) offers a robust coordination site for Pd(OAc)2 centers. Coordination of palladium centers is demonstrated by variety techniques, including X-ray photoelectron spectroscopy and total fluorescence. stable phenanthroline-Pd(II) avoids leaching metal to the reaction medium, where deactivation processes through nanoparti...

In this contribution, we have reported our study on the fine-tuned design and synthesis of new POLITAGs-Pd0 (POLymeric Ionic TAG) catalytic systems with intention defining highly efficient heterogeneous palladium catalysts stabilized by ionic tags able to operate at a very low loading while being fully recoverable/reusable. By varying both support ratio between metal immobilized tag, accessed f...
