Described here is the Ru(III)-promoted amide formation from azides and thioacids, which were shown not to form amides at room temperature in the absence of ruthenium. We believe that a complex formed by Ru(III) increases the reactivity of the thiocarbonyl species and therefore reaction with azides occurs at room temperature, even when less reactive (electron rich and/or sterically hindered) azides
这里描述的是由叠氮化物和硫代酸形成的Ru(III)促进的酰胺,在没有钌的情况下,室温下它们不会形成酰胺。我们认为,由Ru(III)形成的络合物增加了硫代羰基物质的反应性,因此即使在使用较少反应性(电子富集和/或位阻)的叠氮化物时,在室温下也会与叠氮化物发生反应。
