    2-bromoethanol and boron trifluoride etherate in dichloromethane, gave the 2-bromoethyl glycoside. The reactions of the glycoside with methyl 3-mercaptopropionate, methyl 11-mercaptoundecanoate, and octadecanethiol are described, and also its hydrogenolysis to give an ethyl glycoside. The mercaptopropionate-derived, spacer-arm glycoside has been coupled to bovine serum albumin and keyhole limpet haemocyanin
