One reaction developed by this man has a four-membered-ring intermediate that collapses, releasing (
This man developed a method using tetraphenylborate for determining the amount of potassium in seawater. One reaction named for him forms a carbanion next to an oxygen atom, which then rearranges into an alkoxide. An alkoxy-lithium salt is the intermediate in one reaction named for this man, in which an ether transforms into an alcohol under the influence of an alkyl-lithium compound. One reaction developed by this man has a four-membered-ring intermediate that collapses, releasing (*) Ph-three-P oxide as a driving force; that reaction usually has an erythro betaine intermediate, which can be converted into the threo betaine using phenyl-lithium in a modification named for Schlosser. For 10 points, name this German chemist and namesake of a reaction which transforms a carbonyl into an alkene by the use of a phosphonium ylide.
