Butyl chloroacetate iodide

The structures of aryl pyrogallol [4] arenes were confirmed by characterization of their acylated derivatives. Under microwave irradiation, alkylation reactions of aryl pyrogallol[4]arenes with some alkylating reagents such as n-butyl iodide, benzyl chloride, and ethyl a-chloroacetate were completed quickly to yield fully 0-alkyl-ated products. The H NMR spectra and crystal structures showed that the acylated and alkylated aryl pyrogallol [4]arenes existed mainly in rctf(cis-trans-trans) configuration (Yan et al., 2007).
