개요
Trimethylacetaldehyde (also known as Pivaldehyde) is the trimethyl form of acetaldehyde. It is an aldehyde with a sterically bulky R group, the tertiary-butyl group being attached to the carbonyl, >C=O. It is a useful reagent in organic synthesis, pharmaceuticals, agrochemicals and dyestuff. It is useful in streoselective synthesis application as well as in aldol condensation reactions. As a derivative of acetaldehyde, trimethyl acetaldehyde can be used for the production of acetate. It can also be used as the precursor for manufacturing of pyridine derivatives, pentaerythritol, and crotonaldehyde.화학적 성질
Clear colorless liquid용도
Commonly used building block in aldol condensation reactions.주요 응용
Pivaldehyde is a hazardous by-product released from engine exhaust and is often used as a raw material for organic synthesis or as a reagent in chemical reactions. It can be copolymerised with aldehyde anions, such as acrolein, to prepare unsaturated polyacetals, or a TBPB initiated decarbonylative cascade cyclization of ortho-cyanoarylacrylamides with pivaldehyde leads to tert-butyl containing quinolone-2,4(1H,3H)-diones by formation of both C(sp3)–C(sp3) and C(sp3)–C(sp2) bonds. As well as probing the absolute rate constants of its autoxidation, etc[1-3].참고 문헌
