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.

Reduction-substitution reactions of pertechnetate with a class of O,P-bidentate phosphinocarboxylic acid ligands HLn afforded a series of neutral and paramagnetic complexes.The products have been characterized by means of elemental analysis, IR, 1H NMR, UV/VIS and FAB mass spectroscopy, and X-ray crystallography for .The latter crystallizes in the monoclinic space group P21/n with Z = 4, a = 21.718(10), b = 12.954(6), c = 18.038(9) Angstroem and beta = = 106.59(4) deg.The final R value was 0.061.Three deprotonated chelates surround the metal in a distorted-octahedral environment adopting a meridional configuration, and consequently there are two pairs of like donor atoms trans to one another with the remaining phosphorus atom trans to an oxygen atom.Similar reduction-substitution reactions have been performed utilizing the short-lived isotope 99mTc.The physicochemical properties of the resulting 99mTc-labelled species match very well those exhibited by the analogues prepared with the long-lived isotope 99Tc.Thus the chemical structures of <99mTcLn3> and <99Tcn3> analogues are identical.Female Sprague-Dawley rats were injected with pre-purified <99mTcLn3> (n = 1, 2 or 4) and the resulting biodistributions evaluated at different times post injection.All the complexes undergo very low, but significant, brain uptake which decreases with time.
