Input (English): One alternative to this reaction uses diorganochromium and is named for Takai, while one variant is further modified by using KHMDS and is named for Still. The ability of one intermediate to interconvert is called stereochemical drift, and one modification uses a sulfur-containing compound in order to create epoxides. In addition to the Corey-Chaykovsky reaction, and ester version of this reaction was developed by Horner, Wadsworth, and Emmons, while the erythro betaine can be converted to the threo version using phenyllithium in a version named for Schlosser. The formation of an oxaphosphetane drives, FTP, this reaction which uses a phosphonium ylide to create alkenes from carbonyls, named for a German.
Output (English): Science
