WebSulfuric acid (H 2 SO 4) and other reagents, such as n-butanol and acetic acid, were obtained from commercially available sources and used without further purification. The 1 H and 13 C NMR spectra were obtained in D 2 O solvent using a Bruker AVANCE III 400 MHz NMR Spectrometer with TMS as the internal standard. WebWater (BEW) 4:1:2.2 as the solvent system compared with Butanol-Acetic acid-Water (4:1:5) or in Butanol-Acetic acid-Ether-Water (BAEW) 9:6:3:1 because of the solvent systems polarity. Thus BEW (4:1:2.2) is less polar than BAW (4:1:5). The solvent systems used in the order of increasing polarity are as
