1980 Richard C. Tolman Medal Recipient
Herbert D. Kaesz
University of California, Los Angeles

The Recipient: Herbert D. Kaesz received his Ph.d. in 1959 at Harvard where he studied molecular addition compounds of boron and phosphorus under F. G. A. Stone. He stayed for a postdoctoral year to follow his mentor into metal carbonyl chemistry, combining this with a teaching appointment in the Academic Year Institute for High School Teachers at Harvard. This activity carried over into his career at UCLA where he took up his first appointment in 1960 and has risen through the ranks to his present position. He was Director for several Summer Institutes for High School Teachers at UCLA while that program was being funded by the National Science Foundation.

Our speaker came to his interests in chemistry through his father who also held a Ph.D. in that field and through outstanding early teachers such as Louis Serota at Brooklyn Technical High School and R. T. Morrison and R. N. Boyd at Washington Square College, N.Y.U., where he received his B.A.

Professor Kaesz has co-authored over 100 papers in various aspects of organometallic chemistry in which field he pioneered in the synthesis of technetium carbonyl with his first students, Jack C. Hileman and Dale K. Huggins. These studies were followed by extensions into hydrido-metal cluster complexes, and currently into their application to catalysis both in homogeneous and heterogeneous systems. In 1978, he was invited to Japan as a Fellow of the Society for the Promotion of Science and recently was elected a Fellow of the AAAS.

Our speaker is proud of his record of service to the A.C.S. For the local section he served as program chairman of the 1975 Pacific Conference on Chemistry and Spectroscopy and has been a Councilor since 1975, among other duties. In the Division of Inorganic Chemistry, he was Chairman of the Organometallic Sub-Division in 1977 and is currently serving a term as Chairman of the Division. He has been Associate Editor of Inorganic Chemistry since 1968 and is on the editorial boards of various other journals.

1980 Tolman Award Recipient
Herbert D. Kaesz
Professor of Chemistry, UCLA
Award Address: “Transformation of Organic Substrates on Trimetal Cluster Complexes”

Abstract: Synthesis and structure determination for the series of complexes Fe3 (N=CCH3) (CO)9, HFe3 (HN=CCH3) (CO)9 HFe3 (N=CHCH3) (CO)9 and H2Fe3 (NCH2CH3) (CO)9, illustrate the stepwise reduction of acetonitrile on the face of a tri-iron complex. Attempts to extend this series of triruthenium and triosmium complexes have instead led to isolation of carboxamido complexes HM3 (O=CNR2) (CO)10 (M=Ru or Os). Syntheses and interconversions between several isomeric forms of these carboxamido complexes give new insights into elemental reaction steps that could participate in conversions of CO and H2 (syngas) by metal cluster complexes.
