Abstract
Vinyl ether of formula (I) is prepd. by reaction of a dioxolane deriv. of formula (II) with a boric acid ester of formula (III) B(OR)3. In (I), (II) and (III) R = prim., sec. or tert. alkyl; R1, R2 = H or prim., sec. or tert. alkyl; R3 = H, prim. alkyl or opt. substd. phenyl; or R2 + R3 form a 3-10C polymethylene chain opt. substd. by methyl or ethyl gp.; and R4-7 = H or alkyl. Reaction is in the vapour phase at 100-400 (esp. 200-250) deg.C in the presence of an acid heterogeneous catalyst.
