Benzene → p-(5-n-Butyl-1,3-dioxan-2-yl)phenyl p-n-butylbenzoate

Participants

Reaction Steps

A mixture of 2-n-butylpropane-1,3-diol (6.6 g, 0.05 m) and p-(4'-n-butylbenzoyloxy)benzaldehyde (14.2 g, 0.05 m), benzene (100 ml) and a catalytic amount of 4-toluenesulfonic acid was azeotropically refluxed until no more water was collected. The solvent was evaporated and the residue was crystallized from ethanol to yield p-(5-n-butyl-1,3-dioxan-2-yl)phenyl p-n-butylbenzoate (13.4 g 67%) CN 79.2°-80.2° C., NL 160° C.
