Product Details of 2235-01-0《Fe(III)-Exchanged Montmorillonite as Reusable Heterogeneous Protonic Acid Catalyst for Michael Addition of Indole in Water》 was published in 2017. The authors were Matsuzawa, Ryosuke;Nishimura, Shun;Ebitani, Kohki, and the article was included in《ChemistrySelect》. The author mentioned the following in the article:
Fe3+-exchanged montmorillonite (Fe3+-mont) was found to be an effective and a reusable heterogeneous acid catalyst for the Michael addition of indole with Me vinyl ketone at 333 K in H2O to afford 4-(1H-indol-3-yl)butan-2-one in high yields. Investigations on activity of the Fe3+-mont catalyst for deprotection of benzophenone dimethylketal and Meerwein-Ponndorf-Verley reduction of furfural suggested that protonic acid sites of the Fe3+-mont catalyst were responsible for the present Michael addition of indole. The experimental procedure involved many compounds, such as Dimethoxydiphenylmethane (cas: 2235-01-0) .
For example, the most common synthesis of ethers involves the attack of an alkoxide ion on an alkyl halide. This method is called Williamson ether synthesis.Product Details of 2235-01-0
