Academic Editors: Stephen Mansell and Steve Liddle Received: 16 September 2015 / Accepted: 9 October 2015 / Published: 30 October 2015 Abstract: This review article presents the development of organoactinides and actinide coordination complexes as catalysts for homogeneous organic transformations. This chapter introduces the basic principles of actinide catalysis and deals with the historic development of actinide complexes in catalytic processes. The application of organoactinides in homogeneous catalysis is exemplified in the hydroelementation reactions, such as the hydroamination, hydrosilylation, hydroalkoxylation and hydrothiolation of alkynes. Additionally, the use of actinide coordination complexes for the catalytic polymerization of α-olefins and the ring opening polymerization of cyclic esters is presented. The last part of this review article highlights novel catalytic transformations mediated by actinide compounds and gives an outlook to the further potential of this field. Keywords: organoactinides; actinide coordination complexes; homogeneous catalysis; hydroelementations; polymerization of olefins; ROP; activation of heterocumulenes 1. Introduction The beginning of modern organoactinide chemistry is often attributed to the synthesis of 8 uranocene, [(η -C8H8)2U] in 1968, as the analogous compound to ferrocene and other transition metal metallocenes [1,2].

Actinide chemistry is generally only practiced with thorium and uranium for reasons of cost and availability, as well as radioactivity. While all the actinide elements are radioactive, thorium and uranium have α 1 . extremely long half-lives compared to most other metals in the actinide series. Thorium-232 is an -emitter with t/2 14 billion years. Depleted uranium is primarily U-238, which also emits an α-particle when it decays and has a half-life of more than 4 billion years. For these reasons, uranium and thorium are generally considered weakly radioactive [1,2]. Despite the associated complications, actinide chemistry is of great fundamental interest, and has thus blossomed into a rapidly emerging subfield of both inorganic and organometallic chemistry.

ANDREYCHUK, H.B.Sc A Thesis Submitted to the School of Graduate Studies in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy McMaster University © Copyright by Nicholas R. Andreychuk, March 2017. Ph.D. Thesis Nicholas R. Andreychuk Department of Chemistry and Chemical Biology McMaster University DOCTOR OF PHILOSOPHY (2017) McMaster University (CHEMISTRY) Hamilton, Ontario TITLE: Rigid NON-Donor Pincer Ligands in Organoactinide Chemistry AUTHOR: Nicholas R. Andreychuk SUPERVISOR: Prof. David J. H. Emslie NUMBER OF PAGES: xli, 312 ii Ph.D. Thesis Nicholas R. Andreychuk Department of Chemistry and Chemical Biology McMaster University Abridged Abstract The coordination- and organometallic chemistry of uranium complexes bearing the non-carbocyclic ancillary ligand XA2 (4,5-bis(2,6-diisopropylanilido)-2,7-di-tert- butyl-9,9-dimethylxanthene) has been developed as a major focus of this thesis. A number of air-sensitive actinide chloro complexes and alkyl derivatives featuring reactive An–C bonds were prepared, and investigated using a variety of structural and spectroscopic analytical techniques, including X-ray diffraction, NMR spectroscopy, elemental analysis, and electrochemical methods. The research described in this thesis serves to expand the currently underdeveloped, fundamental chemistry of actinide complexes supported by non-carbocyclic (i.e. non-cyclopentadienyl) ligands. For example, the use of the prototypical xanthene-based ligand XA2 has led to neutral dialkyl uranium(IV) complexes which a) react with alkyl anions to yield anionic trialkyl ‘ate’ complexes, b) C–H activate neutral pyridines to yield organouranium(IV) species featuring cyclometalated pyridine-based ligands, and c) react with Lewis acids to yield rare examples of cationic monoalkyl uranium(IV) complexes featuring coordinated arene ligands.

  • The Chemical Complexities of Plutonium David L
    The Chemical Complexities of Plutonium David L. Clark ew people have ever seen plutonium, and far fewer have actually handled or manipu- lated it. Yet this manmade element has arguably altered the course of civilization as Fmuch as copper, bronze, iron, or steel. Within five years of its synthesis, the primary use of plutonium was for the release of nuclear energy in weapons of mass destruction, and it seemed that the new element might lead the human race to the brink of self-annihilation. But instead, plutonium has become a stabilizing agent in global politics, forcing the human race to govern itself without resorting to nuclear war. Never before has a simple chemical element had such a profound impact on the consciousness of mankind. Plutonium has had a similarly humbling impact in the more circumscribed arena of science. Incredibly, it displays physicochemical behaviors that are among the most complex of any element in the periodic table. The pure element exhibits seven distinct crystal phases, is highly reactive, and is known to form compounds, complexes, or alloys with virtually every other element. Molten plutonium is highly corrosive and will slowly react with its container, causing difficulties for handling. When elemental plutonium reacts to give up its valence electrons, it can form a wide variety of positively charged ions with the ability to form up to twelve chemical bonds to other ions or molecules in solution. The element can exhibit five oxidation states, and under certain chemical conditions, four different oxidation states can be present in appreciable amounts simultaneously! No other element displays such a complex chemistry.
