It is used to generate dimethyloxosulfonium methylide by reaction with sodium hydride. [1] The latter compound is used as a methylene-transfer reagent, and is used to prepare epoxides. This compound is commercially available. It may be prepared by the reaction of dimethyl sulfoxide and iodomethane: [2] (CH 3) 2 SO + CH 3 I → (CH 3) 3 SO + I −
Hydrazones are converted to azines when used in the preparation of 3,5-disubstituted 1H-pyrazoles, [12] a reaction also well known using hydrazine hydrate. [ 13 ] [ 14 ] With a transition metal catalyst , hydrazones can serve as organometallic reagent surrogates to react with various electrophiles.
