Hydrazone - Wikipedia
Hydrazones are a class of organic compounds with the structure R 1 R 2 C=N−NH 2 . They are related to ketones and aldehydes by the replacement of the oxygen =O. with the = N−NH 2 functional group. They are formed usually by the action of hydrazine on ketones or aldehydes. Structure of the hydrazone functional group. en.wikipedia.org

hydrazone
hydrazone Chem. (ˈhaɪdrəzəʊn) [ad. G. hydrazon (E. Fischer 1888, in Ber. d. Deut. Chem. Ges. XXI. 984), f. hydrazine + -one.] Any compound which contains the group {b2}N·NH2 (attached to a single carbon atom) and which is thus a condensation product of an aldehyde or ketone with hydrazine; also, any...

Acetone hydrazone
Acetone hydrazone (isopropylidenehydrazine) is the product of condensation of acetone and hydrazine, as typical for hydrazone formation. Acetone hydrazone can be produced on large scale by reaction of acetone azine with hydrazine, a more convenient reaction than direct reaction of acetone wikipedia.org

Hydrazone iodination
Hydrazone iodination is an organic reaction in which a hydrazone is converted into a vinyl iodide by reaction of iodine and a non-nucleophilic base such In the original Barton publication the reaction was optimized by using a strong guanidine base, the inverse addition of the hydrazone to an iodine solution wikipedia.org

Enders SAMP/RAMP hydrazone-alkylation reaction
Mechanism The Enders SAMP/RAMP hydrazone alkylation begins with the synthesis of the hydrazone from a N,N-dialkylhydrazine and a ketone or aldehyde The Nicolaou and coworkers at Scripps Research Institute generated the chiral hydrazone through Enders' hydrazone alkylation reaction with high stereoselectivity wikipedia.org
