An oxime is a chemical compound belonging to the imines, with the general formula RRC=NOH, where R is an organic side-chain and R may be hydrogen, forming an aldoxime, or another organic group, forming a ketoxime. O-substituted oximes form a closely related family of compounds. Amidoximes are oximes of amides with general structure R1C(=NOH)NR2R3.

Oximes are usually generated by the reaction of hydroxylamine with aldehydes or ketones. The term oxime dates back to the 19th century, a combination of the words oxygen and imine.[1]

If the two side-chains on the central carbon are different from each other—either an aldoxime, or a ketoxime with two different "R" groups—the oxime can often have two different geometric stereoisomeric forms according to the E/Z configuration. An older terminology of syn and anti was used to identify especially aldoximes according to whether the R group was closer or further from the hydroxyl. Both forms are ...
