Reaction Steps
A mixture of 5-oxy-1-hexene (9.8 g.), ethylene glycol (18.6 g.), p-toluene sulfonic acid monohydrate (1.56 g.) and benzene (250 ml.) is heated at reflux under a Dean-Stark water separator. After 2 hrs., the reaction mixture is washed with water and the organic layer is separated, dried with magnesium, and evaporated in vacuo. Distillation of the residue gives 5-ethylenedioxy-1-hexene (90% yield) b.p. 34°-37°/1.5 mm. nmr (CDCl3)δ: 1.27 (s, CH3), 1.5-2.4 (m, CH2 --CH2); 2.83 (s, --O--CH2 --CH2 --O); 4.80-6.1 (m, CH2 =CH--). IR (film)μ: 6.06 (CH2 =CH--).
