394 complex between nickel and the olefin being an essential step in the preparation of the catalyst. In 1970, Lemkuhl and Leuchte (J. Organomet. Chem. 23 (1970) C30) found that it was possible to prepare a butadiene trimerization catalyst from Ni(acac)2 using an electrochemical method. When the method was tried in TH Twente using Pt electrodes to electrolyse Ni(acacj2 dissolved in tetrahydrofuran in the presence of propadiene, it did not yield an active catalyst. However, when an aluminium anode was used, an active material was obtained. (It is probable that any metal that readily forms an acetylacetonate could be used instead of Al.) Van Ommen and his colleagues suggest that the following reactions may occur: Anode: Al + 3/2Ni(acac)2 -f Al(acac),, t 3/2Ni2' t 3e Cathode: ;;$~i[;~~:)~a:a~_e + Cell Reaction:
Al t 3/21li(acac)2 -t Al(acac)3 t 3/2Ni(O)
Because no nickel deposit was observed on the cathode, it is concluded that the Ni(0) formed reacts directly with the olefin to form a nickel -olefin complex which is the catalyst for the polymerization reaction. The electrolysis method (which must be carried out in the absence of oxygen) provides a route for the preparation of a catalyst in solution without the addition of other organometallic compounds such as aluminium alkyls. Conferences
on Coal
The Pittsburgh Energy Technology Center of the United States Department of Energy will host two conferences on coal-related topics in 1983 (see Calendar). The first concerns mainly coal-slurry combustion and technology and will deal with all aspects of slurry preparation and characterisation, reactions and additives as well as emission considerations and the economics and commercialisation aspects of the subject. The second is rather broader and deals, inter-alia, with coal liquefaction, combustion and gasification, the chemistry of synthesis gas and the catalysis of coal conversion.

Amoco Oil Company have recently announced the sponsorship of the Robert Burwell Lecturership in Catalytic Chemistry. Professor Burwell, who retired from his post of Ipatieff Professor of Chemistry in Northwestern University, Evanston, Illinois, in 1980 has served Amoco and its parent company, Standard Oil Company (Indiana) as a consultant since 1950 and is credited by them with many valuable contributions to their research programme. After obtaining his bachelor of science degree from St. John's Colleqe, Annapolis, Md., in 1932 and a doctorate in physical chemistry from Princeton University in 1936, he joined the staff of-Northwestern in 1939 and was chairman of the chemistry department from 1952 to 1957 and Ipatieff Professor from 1970 to 1980. Professor Burwell has published more than 100 scientific papers and review articles and has lectured throughout the world on various aspects of catalvsis and surface chemistry. His contributions to the subject were recognised in 1973 by the award of the Kendall Award in Colloid and Surface Chemistry and he was president of the Catalysis Society of North America from 1973 to 1977. Since his retirement, he has continued research, lecturing and consulting at Northwestern and at Universities in Europe. He and his wife, Elise, have two daughters. The lecturer-ship is designed to recognise and encourage individual contributions in the field of catalysis and to make the awardee available to the membership of local catalysis societies through a lecture tour. The recipient will be selected on the basis of his or her contributions to the catalytic literature and the timeliness of these contributions, emphasis being placed on discovery and understanding of catalytic phenomena, catalytic reaction mechanisms and the identification and description of catalytic sites and species. The award consists of a prize of $5000 and $2500 for expenses and will be made every other year. startinq in 1983, selection being made by-the Catalysis Society. Professor Burwell himself will be the first recipient of the award.
