hydroxylimino
Hydroxylimino refers to a functional group with the structure R2C=NOH, where R represents any organic substituent or hydrogen atom. This group is also known as an oxime. Oximes are derivatives of aldehydes and ketones where the carbonyl oxygen is replaced by a hydroxylimino group. The formation of oximes is a common reaction in organic chemistry, typically achieved by reacting an aldehyde or ketone with hydroxylamine or its salts, often under acidic conditions. This reaction is a condensation, releasing a molecule of water.
The nitrogen atom in the hydroxylimino group is sp2 hybridized and is bonded to one organic group
Oximes are important intermediates in organic synthesis. They can be reduced to primary amines, rearranged to
