Friedel–Crafts benzylation and phenethylation reactions of several aromatic compounds with benzyl and phenethyl benzothiazol-2-yl carbonate derivatives were carried out in the presence of scandium triflate (Sc(OTf)3) as a catalyst. Suitable combinations of the leaving group of carbonates and acid promoters that generate cationic alkyl species were examined.
在三氟甲磺酸钪(Sc(OTf)3)作为催化剂存在下,进行了几种芳香族化合物与苄基和苯乙基苯并噻唑-2-基碳酸酯衍生物的Friedel-Crafts苄基化和苯乙基化反应。检查了碳酸酯离去基团和产生阳离子烷基物质的酸促进剂的合适组合。
