A novel gold(III) and TfOH-cocatalyzed reaction of ortho-alkynylbenzaldehydes with cyclopropenes was described for the synthesis of a variety of functionalized benzo[7]annulene derivatives in a highly stereoselective manner. This reaction underwent tandem [4+2] cycloaddition/ring expansion to achieve the construction of seven-membered-carbocycles, along with the cleavage of double bond of cyclopropenes. The reaction featured simple operations, com. available catalysts and broad substrate scope with good efficiencies. This study involved multiple reactions and reactants, such as 5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3HPLC of Formula: 1186603-47-3).
5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.HPLC of Formula: 1186603-47-3
