A versatile and efficient palladium-meta-terarylphosphine catalyst for the copper-free sonogashira coupling of (hetero-)aryl chlorides and alkynes

A novel meta-terarylphosphine ligand, CyPhine, was developed and found to be a highly active promoter of copper-free Sonogashira cross-coupling reactions when combined in situ with a palladium source. The evolutionary m-terarylphosphine ligand architecture was able to impose significant performance advantages over its biarylphosphine congeners. An expedient and versatile protocol was also devised with an emphasis on substrates applicable to the fine-chemicals industry by featuring a diverse range of challenging, electronrich aryl chlorides and terminal alkynes. The Pd-CyPhine catalyst was able to deliver products in excellent yields with efficient substrate utilization, which minimizes the generation of commonly formed byproducts, and the reaction is tolerant of a variety of substrates with unprotected functional groups.

Ion-Mobility Mass Spectrometry for the Rapid Determination of the Topology of Interlocked and Knotted Molecules

A rapid screening method based on traveling-wave ion-mobility spectrometry (TWIMS) combined with tandem mass spectrometry provides insight into the topology of interlocked and knotted molecules, even when they exist in complex mixtures, such as interconverting dynamic combinatorial libraries. A TWIMS characterization of structure-indicative fragments generated by collision-induced dissociation (CID) together with a floppiness parameter defined based on parent- and fragment-ion arrival times provide a straightforward topology identification. To demonstrate its broad applicability, this approach is applied here to six Hopf and two Solomon links, a trefoil knot, and a [3]catenate.

Synthesis, X-ray, spectroscopic and a preliminary Suzuki coupling screening studies of a complete series of dppfMX2 (M=Pt, Pd; X=Cl, Br, I)

A complete series of dppfMX2 (M=Pt, Pd; X=Cl, Br, I) compounds have been synthesized using different routes, and characterized fully. The synthesis of dppfPdI2 has been achieved by reacting Pd(COD)Cl2 with dppf in the presence of NaI. X-ray structures of dppfPdBr2 and dppfPdI2 have also been reported for the first time in this study. A preliminary Suzuki coupling screening study reveals that dppfPdX2 compounds are superior to the conventional Ph3P-based catalysts and bidentate phosphine-based ligands. Reactions carried out under in situ conditions also gave a similar trend, but their respective activities were much lower than that of the fully formed catalysts.

On the formation of Pd(II) complexes of Trost modular ligand involving N-H activation or P,O coordination in Pd-catalyzed allylic alkylations

Specific chiral ligands have been designed by Trost et al. to perform enantioselective Pd-catalyzed allylic alkylations. It is shown that the Pd(0) complex formed by addition of the Trost ligand (4) to Pd0(dba)2 is not stable in most solvents (acetone, DMF, CH2Cl2). Indeed, Pd0(dba)(4) leads to the formation of a stable PdII complex 5 (X-ray structure), likely by activation of the two N-H bonds of the ligand by the Pd0 centre. The formation of the PdII complex competes with the reaction of Pd0(4) with (E)-PhCH{double bond, long}CH-CH(OAc)-Ph, excluding any investigation of the kinetics of the latter reaction. The ionization steps from intermediate (eta2-PhCH{double bond, long}CH-CH(OAc)-Ph)Pd0(4) were found to be very slow. The cationic P,P complex [(eta3-Ph-CH-CH-CH-Ph)Pd(4)]+, expected to be generated by addition of 2 equiv. of 4 to the precursor [(eta3-Ph-CH-CH-CH-Ph)Pd(mu-Cl)]2, in the presence of a chloride scavenger, leads to a complex mixture whereas addition of 1 equiv. of 4 affords a stable bis-cationic PdII complex {[(eta3-Ph-CH-CH-CH-Ph)Pd]2(4)]}2+, 2 (BF4-) (X-ray structure) via a P,O complexation of each allyl-Pd moieties. This dissymmetric P,O coordination will favour the enantioselectivity of Pd-catalyzed allylic alkylation of (E)-PhCH{double bond, long}CH-CH(OAc)-Ph by the control of the regioselectivity of the nucleophilic attack onto the allylic ligand which is responsible of the enantioselectivity of the overall catalytic reaction.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C34H28O2Pd, you can also check out more blogs about32005-36-0
