Pt(PBut3)2 and Pd(PBut 3)2 react with PtRu5(CO)16 (mu6-C) (4) to yield the new cluster complexes, PtRu5(CO)16(mu6-C) [Pt(PBut3)] (5); PtRu5(CO) 16(mu6-C)[Pt(PBut3)] 2 (6); PtRu5(CO)16 (mu6-C)[Pd(PBut3)] (7) and PtRu5(CO)16(mu6-C) [Pd(PBut3)]2 (8). All four complexes have been characterized crystallographically. Compounds 5 and 7 are structurally similar and contain a M(PBut3) group bridging an Ru-Ru edge of the original cluster of 4. Compounds 6 and 8 contain two M(PBut3) groups. One group bridges an Ru-Ru edge as found in compounds 5 and 7. The other M(PBut3) group bridges one of the Pt-Ru edges of the original cluster of 4. All four compounds can be viewed as M(PBut3) adducts of 4 because no ligands were lost from 4 in the course of these addition reactions.

Reaction sequences started by a ruthenium-catalyzed enyne cross-metathesis of bromo-substituted phenylacetylenes with ethane, followed by a regiodiverse cobalt-catalyzed Diels-Alder reaction with phenyl alkynyl pinacolboronic esters, and DDQ oxidation gave the desired bifunctional terphenyl derivatives in good yields and regioselectivities. These terphenyl derivatives which were decorated with solubility promoting alkyl-substituents were subsequently subjected to Suzuki polycondensations generating soluble poly(phenylene)s of high molecular weight. Even challenging sterically hindered ortho-bromo-substituted arene moieties could be applied successfully in the Suzuki polycondensations. The regiodivergent cobalt-catalyzed step could be used in a divergent synthesis of poly(phenylene)s with different architectures starting from identical educts. Modifications in the starting materials, which can be easily introduced, will allow the flexible generation of more complex polymers in the future.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 53199-31-8 is helpful to your research. Synthetic Route of 53199-31-8

The compound Pd(eta3-1-PhC3H4) (eta5-C5H5) reacts essentially quantitatively with a variety of phosphines L to form cross-coupling catalysts of the type PdL2 and has recently been shown to be a much more effective catalyst precursor for Suzuki-Miyaura cross-coupling reactions in comparison to more commonly utilized precursors such as Pd(PPh3)4, Pd 2(dba)3, and Pd(OAc)2, which do not effectively generate two-coordinate species PdL2. This advantage is expected to apply also to e.g. Heck-Mizoroki and Sonogashira cross-coupling reactions, both of which are generally believed to be catalyzed by species of the type PdL 2. Therefore, comparisons of the efficacies of catalyst systems based on Pd(eta3-1-PhC3H4)(eta5- C5H5), Pd(PPh3)4, Pd 2(dba)3, and Pd(OAc)2 are made utilizing the conventional coupling reactions of aryl halides with methyl acrylate and styrene for Heck-Mizoroki coupling and with phenylacetylene for Sonogashira coupling. As anticipated, catalyst systems based on Pd(eta3-1-PhC 3H4)(eta5-C5H5) are found to be significantly more active.

(E)- and (Z)-beta-borylallylsilanes by alkyne silaboration followed by regio- and stereoselective double-bond migration

Double take: beta-Borylallylsilanes have been synthesized by the regioselective silaboration of terminal alkynes followed by palladium-catalyzed double-bond migration of the resulting beta-borylalkenylsilanes (see scheme). The stereoselectivity of the double-bond migration can be controlled by additives, thus leading to the stereocomplementary synthesis of (E)- and (Z)-beta-borylallylsilanes. Copyright

1,6-Diene complexes of palladium(0) and platinum(0): Highly reactive sources for the naked metals and [L-M0] fragments

The complexes (cod)MCl2 (M = Pd, Pt; cod = cis,cis-1,5-cyclooctadiene) react with Li2(cot) (cot = cyclooctatetraene) in a 1,6-diene/diethyl ether mixture (1,6-diene = hepta-1,6-diene, diallyl ether, dvds (1,3-divinyl- 1,1,3,3-tetramethyldisiloxane)) to afford the isolated homoleptic dinuclear Pd0 and Pt0 compounds Pd2(C7H12)3 (1), Pd2(C6H10O)3·C6H10O (2′; 2: Pd2(C6H10O)3), Pd2(dvds)3 (3), and Pt2(C7H12)3 (4). When 1-4 are treated with additional 1,6-diene the equally homoleptic but mononuclear derivatives of type M(1,6-diene)2 (5-8) and with ethene the mixed alkene complexes (C2H4)M(1,6-diene) (9-12) are obtained in solution. Complexes 1-12 react with donor ligands such as phosphanes, phosphites, or (t)BuNC to give isolated complexes of types L-M(1,6-diene) (13-41), which have also been prepared by other routes. In all complexes the metal centers are TP-3 coordinated: complexes 1-4 contain chelating and bridging 1,6-diene ligands, whereas the other complexes contain a chelating 1,6-diene ligand and an eta2-alkene (5-12) or eta1-donor ligand (13-41). Of the studied 1,6-diene complexes the hepta-1,6-diene derivatives are most reactive, while the diallyl ether complexes are often more convenient to handle. The readily isolable dinuclear hepta-1,6-diene and diallyl ether complexes 1, 2′, and 4, and their mononuclear pure olefin derivatives are among the most reactive sources for naked Pd0 and Pt0. The corresponding L-M(1,6-diene) complexes are equally reactive precursor compounds for the generation of [L-M0] fragments in solution, which for M =Pd are available otherwise only with difficulty. The results are significant for the operation of naked Pd0 and L-Pd0 catalysts in homogeneous catalysis.

Palladium-catalyzed arylation of open-cage silsesquioxanes toward thermally stable and highly dispersible nanofillers

Incompletely condensed polyhedral oligomeric silsesquioxanes (IC-POSS) are promising building blocks for the development of organic-inorganic hybrid materials. Pd-catalyzed arylation of heptaphenyl IC-POSS has been developed to introduce various substituents on to the open moieties without using highly moisture-sensitive chlorosilane derivatives. The substituents drastically affected the thermal behavior of the corresponding IC-POSSs. The obtained IC-POSSs were well dispersed in poly(methyl methacrylate) (PMMA) matrices to tune the thermal and optical properties of their composite films.
