Trimethyl orthoformate → 1-Methoxycyclooct-1-ene

Participants

Reaction Steps

In the presence of 0.2 g of para-toluenesulfonic acid, 16.5 g (0.13 mol) of cyclooctanone and 16.5 g (0.15 mol) of trimethyl orthoformate were stirred at room temperature for four hours. The resultant mixture was heated at 100° C. for 14 hours. The vacuum distillation of the mixture gave 13.7 g (75% in yield) of 1-methoxycyclooctene having a boiling point of 83° to 88° C./27 mmHg.
