PHILADELPHIA, PA 19104 The 19S6 Most-Cited Chemistry Articles: Enzymes in Organic Synthesis and Odd-Cluster Soot Up, While Superconductivity Disappears (For Now) Number 27 jll!y 8, 1991 Current Contents Q readers are generally aware of our amual series listing papers that have been “most-cited” in the last two or three years. For reasons that have been dis- cussed frequently,I the “immediacy” of most hot papers in chemistry can lag by more than a year behind those in physics or the life sciences. The essay that follows should have appeared last year, shortly after the appearance of the 1989 Science Citation Index @. However, in publishing it now, we are able to include supplemental informa- tion on the status of the citations to these papers for the years 1989 and 1990. The delay in publishing this putative list of Cita- tion Classics @ in chemistry demonstrates more forcefully the characteristic delay mentioned above. The most-cited paper on the list received 99 citations by the end of Zvi Sza@m 1988. By the end of 1990, it had received an additional 138. term born out of a conversation I had with AS you can see, chemists, earth scientists, Robert K.
