These reactions allow the obtaining of salts with high added value which could be used in the development of biomaterials for dental use. The objective of this work was to obtain calcium, magnesium and zinc resinates from the resin acid obtained from the Cuban pine resin by metathesis reaction for possible use in the development of biomaterials. The products obtained were evaluated by elemental analysis, X-ray powder diffraction, infrared spectroscopy, scanning electron microscopy associated with electron dispersion spectroscopy, nuclear magnetic resonance and biological tests (antibacterial activity).

  • Mechanistic Considerations on the Hydrodechlorination Process of Polychloroarenes
    Chapter 3 Mechanistic Considerations on the Hydrodechlorination Process of Polychloroarenes YoshiharuYoshiharu Mitoma, Mitoma, Yumi KatayamaYumi Katayama andand CristianCristian Simion Simion Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.79083 Abstract Defunctionalization of organochlorines through reductive dechlorination (also known as hydrodechlorination—replacement of chlorine atoms by hydrogen—is one of the main methodologies used in the detoxification of these harmful compounds. Most of the pub- lished papers on this particular matter focused on specific reagents, reaction conditions, and mainly result efficiency. Some of the authors were also concerned with reaction -path ways (e.g., the order in which chlorine atoms were removed from a polychlorinated aro- matic substrate—polychlorinated biphenyls, PCBs; polychlorinated dibenzo-p-dioxins, PCDDs; or polychlorinated dibenzofurans, PCDFs). However, the papers that dealt with the investigation of reaction mechanism were rather scarce. This chapter presents the advances made by researchers in understanding, from a mechanistic point of view, the hydrodechlorination process, along with our own assumptions. In doing so, it would be easier to predict the behavior of such compounds in a specific environment, showing more clearly the scope and limitations of each process, depending on the reaction condi- tions and reagents. Keywords: hydrodechlorination, reaction mechanism, metal/hydrogen donor 1. Introduction Most chlorinated and especially polychlorinated arenes (such as polychloro-dibenzo-p-diox- ins 1, polychloro-dibenzofurans 2, or polychlorobiphenyls 3) are persistent organic pollutants (POPs) that are harmful to both man and the environment [1–5]. © 2016 The Author(s).

Tel: +1-709-864-8089, Fax: +1-709- 864-3702, E-mail: [email protected] Contribution For Special Issue on “Modern Canadian Inorganic Chemistry” Abstract A novel lithium complex was prepared from the reaction of 1,4-bis(2-hydroxy-3,5-di-tert-butyl- BuBuIm benzyl)imidazolidine H2[O2N2] (L1H2) with n-butyllithium to provide the corresponding 7 tetralithium amine-bis(phenolate) complex {Li2[L1]}2•4THF, 1. Variable temperature Li NMR revealed that this complex is labile in solution, dissociating at elevated temperatures to afford two dilithium entities. Additionally, 7Li MAS NMR was performed on 1 to provide information regarding the lithium coordination environment in the bulk solid-state. The reactivity of 1 was assessed in the ring-expansion polymerization of ε-caprolactone (ε-CL), which was first order in ε-CL with an activation energy of 50.9 kJmol-1.

Santiago, Carmen Urbaneja, Eleuterio Álvarez, Elena Ávila, Pilar Palma and Juan Cámpora * We report a series of organometallic nickel and palladium complexes containing iminophosphine ligands R2PCH2C(Ph) = N-Dipp (Dipp = 2,6-diisopropylphenyl; R = iPr, La; R = Ph, Lb; and R = o-C6H4OMe, Lc), synthesized by ligand exchange or oxidative addition reactions, and we investigate the capacity of such ligands to undergo reversible deprotonation to the corresponding phosphinoenaminato species. In the attempted ligand exchange reaction of the nickel bis(trimethylsilyl)methyl precursor [Ni(CH2SiMe3)2Py2] with Lb, the iminophosphine acts as a weak acid rather than a neutral ligand, cleaving one of the Ni–C bonds, to afford the phosphinoenaminato complex [Ni(CH2SiMe3)(L’b)(Py)] (L’b = conjugate base of Lb).

This result led us to investigate the chloride abstraction from the (NHC)Ir(COD)Cl system in detail. We show how the outcome of this ubiquitous reaction is dependent on a fine balance between nucleophilicity of the weakly coordinating anion (WCA) and the polarity / coordinating ability of the reaction medium. A frequent- ly encountered alternative to using silver salts is also presented and compared. The experimental difference in the reactivities of cationic catalysts in a representative intramolecular hydroamination reaction shows how cationic Ir-Ag adduct can fail to deliver the reaction product through what appears to be a stabilization of the catalytically inactive iridium-silver intermediate by the educt. 1.
