nest: The first thiocarboxylation of styrenes and acrylates with CO2 to generate important β-thioacids was realized by using visible light as a driving force and catalytic iron salts as promoters. This multicomponent reaction features broad substrate scope, mild reaction conditions, and high regio-, chemo-, and diasteroselectivity. Mechanistic studies indicate that a radical pathway can account for the
一个人飞过了COO - COOH的巢穴:利用可见光作为驱动力,并用催化铁盐作为促进剂,实现了苯乙烯和丙烯酸酯与CO 2的第一次硫代羧化反应,生成重要的β-硫代酸。这种多组分反应具有广泛的底物范围,温和的反应条件以及高的区域选择性,化学选择性和非对映选择性。机理研究表明,自由基途径可以解释异常的区域选择性。
