Discoveries at Risk

New discoveries at the interface of boron and carbon chemistries*

The continued growth of polyhedral borane chemistry is illustrated by the successful synthesis of [closo-B12(OH)12] 2– by the H2O2 oxidation of [closo-B12H12] 2–. The hydroxylated species reacts with common organic reagents to produce 12-fold degenerately substituted carboxylate esters, ethers, and carbamate esters. The ether derivatives undergo facile and reversible redox reactions in which th...

Dr. Winternitz and Pediatrics at Yale *

The Department of Pediatrics in Yale University was established on a full-time basis and as a major clinical discipline on July 1, 1921. Dr. Milton C. Winternitz was Dean of the School of Medicine and Dr. Edwards A. Park was founding chairman of the department. The clinical service included patients with infectious diseases, as well as those with general pediatric disorders, and an out-patient ...
