Synthesis and Structure of Alcohols

Ch10 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.

Reactions of Alcohols - Rutgers University

Dehydration Reactions of Alcohols Dehydration of alcohols requires an acidic catalyst to convert the hydroxyl into a good leaving group – this is an equilibrium reaction. It is possible to force the equilibrium to the right (alkene) by removing one or both of the products.

Carboxylic Acids - Rutgers University

Carboxylic acid derivatives differ in the nature of the group bound to the acyl group. -OH is an acid-Cl is the acid chloride-OCOR' is the anhydride-OR' is the ester-NR 2 is the amide Nucleophilic acyl substitution can interconvert all of these different acid derivatives.

Ketones and Aldehydes - Rutgers University

Alkenes can be cleaved by ozone (followed by a mild reduction) to generate aldehydes and/or ketones. ... Summary The base catalyzed addition reactions to carbonyl compounds result from initial attack of a strong nucleophile, whereas the acid catalyzed reactions begin with the protonation of the oxygen, followed by attack of the weaker nucleophile.

Organic Chemistry I - Rutgers University

Bronsted-Lowry Lewis Arrhenius Definition (pre-1900) An acid is a substance that dissociates in water to give H 3 O+ ions. (Stronger acids like H 2 SO 4 were assumed to dissociate more than weaker acids like CH 3 CO 2 H). A base is a substance that dissociates in water to give …

Ketones and Aldehydes - Rutgers University

aldehydes (two alkyl substituents vs. one alkyl substituent). (Aldehydes more reactive than ketones). Steric Reason The electrophilic carbon is the site that the nucleophile must approach for reaction to occur. In ketones the two alkyl substituents create more steric hindrance than the single substituent that aldehydes have.
