Heterogenized manganese catalyst for C-, and N-alkylation of ketones and amines with alcohols by pyrolysis of molecularly defined complexes was written by Ahmad, Muhammad Sohail;Inomata, Yusuke;Kida, Tetsuya. And the article was included in Molecular Catalysis in 2022.Formula: C8H10O2 This article mentions the following:
Series of organic transformations are known to be catalyzed by molecularly well-defined homogeneous catalysts, however, it is difficult to recycle. Meanwhile, heterogeneous catalysts are required in many industrial processes due to their stability, and recyclability, but it is challenging to control on a mol. level. Herein, we set out the conversion of homogenous manganese complex into heterogeneous manganese-based catalyst via pyrolyzing the pre-formed crystalline polymer. The catalyst thus produced are then utilized for C-C/C-N bond-forming reactions, such as alkylation of ketones and/or amines, utilizing primary alcs. as an alkylating agent, under nearly mild conditions liberating water as the sole byproduct. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Formula: C8H10O2).
(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.Formula: C8H10O2
