3-Pentylmagnesium bromide solution
3-Pentylmagnesium bromide solution (CAS: 4852-26-0; C5H11BrMg; MW: 175.35) is a highly reactive organometallic compound supplied by Tech Serve Solutions. As a Grignard reagent, it is extensively used in organic synthesis for forming new carbon-carbon bonds. It is typically employed in reactions requiring nucleophilic addition to carbonyl compounds and alkylation of electrophiles. This reagent is supplied as a solution in diethyl ether, demanding careful handling due to its pyrophoric and water-reactive nature.
Carbon-Carbon Bond Formation
3-Pentylmagnesium bromide is a key Grignard reagent for creating new carbon-carbon bonds. It readily reacts with aldehydes, ketones, esters, and epoxides to introduce the pentyl group into organic molecules.
Synthesis of Alcohols
Reaction with aldehydes and ketones yields secondary and tertiary alcohols, respectively. This is a fundamental transformation in the synthesis of complex organic structures.
Alkylation Reactions
As a strong nucleophile, it can alkylate suitable electrophilic substrates, expanding the carbon skeleton of organic compounds.
Preparation of Carboxylic Acids
Carboxylation of 3-pentylmagnesium bromide with carbon dioxide followed by acidic workup yields pentanoic acid derivatives.
