PROCEDURE

实验过程

An equimolar mixture of p-trifluoromethylbenzaldehyde and 2-pentylpropane-1,3-diol in toluene is boiled on a water separator with catalysis by p-toluenesulfonic acid. When the water separation is complete and after conventional work-up, p-(trans-5-n-pentyl-1,3-dioxan-2-yl)trifluorotoluene, m.p. 44.3°, Δε=+12.9, is obtained.
