A range of ruthenium-arene compounds with chloride, bromide or iodide ligands were prepared and tested as catalysts for the homogeneous redox neutral alkylation of tert-butylamine with phenethyl alcohol, and compared to the previously reported catalyst [RuCl2(p-cymene)]2, in the presence of the diphosphine 1,1?-bis(diphenylphosphino)ferrocene (dppf). The best catalytic activities were obtained with ruthenium iodide compounds. The formation of either [RuX(p-cymene)(dppf)][X] or [(RuX2(p-cymene)) 2(dppf)] (X = halide) under the catalytic conditions employed was investigated. Copyright

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.Recommanded Product: 12150-46-8, you can also check out more blogs about12150-46-8

Among the many types of transition-metal-catalysed C-C bond forming reactions, olefin metathesis is without a doubt one of the most thriving fields in modern organic synthetic chemistry. This is due to a wide range of transformations that are possible by olefin metathesis with commercially available and user friendly catalysts. Until recently, the formation of tetrasubstituted double bonds via olefin metathesis is considered as a very challenging topic. Although much attention has already been given in the last two decades to improve this transformation by the modification of catalysts, optimising the conditions, substrate modification and so on, however, none are universally attractive so far. So the field is still quite open and looking for a simple and general solution that suits all challenging substrates. In this context, this review is an attempt to provide a broad but digestible overview of tetrasubstituted C-C double bond formation via olefin metathesis, with an emphasis on the recent developments achieved in this area. These developments are actually signifying the great potential for further advancement of this exhilarating research field.

Abstract: Reaction of Na2[PdCl4] with two equivalents of 4,5-benzo-3H-1,2-dithiole-3-thione (btt) affords cis-[PdCl2(kappa1-btt)2] (1), which provides a convenient entry into mixed-ligand btt complexes. Addition of one equivalent of a range of diamines or diphosphines gives the salts [Pd(kappa1-btt)2(kappa2-diamine)]Cl2 (2a?d) (diamine = en, dap, bipy, phen) and [Pd(btt)2(kappa2-diphosphine)]Cl2 (3a?c) (diphosphine = dppe, dppp, dppf) in good yields. In contrast, two equivalents of dppm result in [Pd(kappa1-btt)2(kappa1-dppm)2]Cl2 (4), where the diphosphine binds in a monodentate fashion. Two equivalents of PPh3 result in a mixture of cis- and trans-isomers of [Pd(kappa1-btt)2(PPh3)2]Cl2 (5a?b) (ca. 1:5 ratio); the pure trans-isomer 5b was isolated by ion-exchange chromatography. The cis-isomer 5a could be synthesized independently from the reaction of cis-[PdCl2(PPh3)2] with two equivalents of btt. In all of these complexes, the btt ligand binds in a monodentate manner through the exocyclic thione sulfur. The anti-tumor activities of representative examples, cis-[PdCl2(kappa1-btt)2] (1), cis-[Pd(kappa1-btt)2(kappa1-dppm)2]Cl2 (4) and cis-[Pd(kappa1-btt)2(PPh3)2] (5a), were evaluated by cell proliferation assays and phase-contrast microscopy against prostate cancer cell lines PC3, DU145 and LNCaP, with complexes 1 and 4 showing potent anti-proliferative effects (TGI values of 19.2 and 21.1?mug/mL, respectively) against LnCaP cells.
