Acetaldehyde Chloral hydrate Benzaldehyde Aceton Acetophenone It contains variety of chemical compound including benzoate ceosol benzaldehyde y terpineol nerolidol. Aldehydes. The term Aldehyde come for the words . al. cohol . dehy. drogenation. . Preparation: Oxidation of primary alcohols according to the following equation:. Note: Oxidation can be considered as removal of hydrogens. Dr. Talat R. Al-Ramadhany. Introduction . Aldehydes are compounds of the general formula . RCHO. ;. Ketones are compounds of the general formula . RR´CO. . The groups R and R´ may be aliphatic or aromatic. . 18-4. Alkylation of enolates can be difficult to control.. The alkylation of an aldehyde or ketone enolate is an example of a nucleophilic substitution reaction.. The alkylation of aldehydes and ketones is complicated by several unwanted side reactions..
