实验过程

If the procedure described in Preparation I is followed starting from 1.6 g (6.5.10-3 mol) of 3,5-bis(trifluoromethyl)benzenethiol, 1.64 g (6.5.10-3 mol) of mercuric cyanide, Hg(CN)2, and 2.54 g (7.5.10-3 mol) of 2,3,4-tri-O-acetyl-5-thio-α-D-xylopyranosyl bromide, 1.2 g (yield: 35.7%) of the expected product are obtained. M.p.=201° C.
