A reaction formulated by this organic chemist involves the reaction of an allylic alcohol with an orthoamide which subsequently undergoes Claisen rearrangement to form a gamma,delta-unsaturated amide, which is generally referred to as his variant of the Claisen reaction.

Another reaction named for him involves the reaction of a thioester with an alpha-halocarbonyl and subsequent rearrangement to form a 1,3-dicarbonyl compound - that is his 'sulfide contraction'. An alpha,beta-epoxyketone is reacted with an aryl sulfonylhydrazine and resulting fragmentation results in an alkyne and ketone in a reaction named for him and Tanabe. The salt named for him is widely used in Mannich-type reactions and is the iminium product of the condensation of formaldehyde and dimethylamine. FTP, name this famous chemist who is often credited for developing, with Robert Woodward, a successful synthesis of vitamin B12 in the early 1960s.
