Since water is “removed”

Oxidation Reactions of Sugars
butane.chem.uiuc.eduhalf reactions. Oxidation Reactions of Sugars Oxidation of Alcohol Groups Alcohols are organic molecules with the C-OH functional group and sugars always have many of these groups. Oxidizing agents, such as chromium trioxide, convert the C-OH group of alcohols into the C=O group of an aldehyde or a ketone.
Synthesis and Structure of Alcohols
crab.rutgers.eduCh10 Alcohols; Struct + synth (landscape).docx Page 18 Other Selected Organometallic Reactions Corey-House Reaction This is a good synthetic way to join two alkyl groups together. A lithium dialkylcuprate reacts with an alkyl halide. The lithium dialkylcuprate is formed using the alkylithium reagent and copper (I) iodide.
