Title | Halpern, Jack: certificate of election to the Royal Society |
Description | Citation typed. Letter attached to certificate. |
Citation | Professor J. Halpern is particularly distinguished for his researches into the kinetics and mechanisms of homogenous catalysis by transition metal ion complexes, and especially of homogeneous hydrogenation. He has also made important contributions to our knowledge of the kinetics and mechanisms of inorganic reactions generally, and notably of electron transfer and substitution reactions in coordination compounds. Starting from Calvin's (1938) discovery of homogeneous hydrogenation, catalysed by cuprous acetate in quinoline, in 1953 he discovered and studied many new hydrogenation systems, especially those involving aqueous ions, such as ruthenium (II), and established the detailed mechanisms by kinetic arguments. More recently he has extended his studies into the field of coordination complexes and has applied ideas derived from homogeneous catalysis to heterogeneous catalysis. His work has been characterised by clear exposition and a wide grasp of chemical ideas over the fields of inorganic, physical and organic chemistry. |
