William D. Emmons
William D. Emmons was an American chemist and published with William S. Wadsworth a modification to the Wittig-Horner reaction using phosphonate-stabilized carbanions, now called the Horner-Wadsworth-Emmons reaction or HWE reaction or Horner-Wittig reactionLife
Emmons studied at the University of Minnesota and served in the Pacific in World War II and avoided being drafted for the Korean War by working for the Redstone Arsenal Research of Rohm and Haas where he worked until his retirement in 1989.Work
In work undertaken in collaboration with Arthur F. Ferris, Emmons reported that in situ generated trifluoroperacetic acid was capable of oxidising aniline to nitrobenzene, an observation which pioneered the applications of this peroxy acid as an oxidising agent in organic chemistry. Emmons went on to discuss the preparation of trifluoroperacetic acid and numerous applications of the new reagent, including: oxidation of nitrosamines to nitramines; the Baeyer–Villiger oxidations of ketones to esters; and the conversion of alkenes to epoxides or to glycols.
