Olefin metathesis reactions of some aromatic dienes with ortho- and meta-disubstitution, formation of 10-, 12-, 14-, and 17-membered cyclic compoundsand isomerization of an allylic alcohol

Some aromatic dienes with ortho- and meta-disubstitution have been subjecte d to olefin metathesis reactions. Compounds having allylphenyl groups subst ituted at their ortho positions successfully cyclized into 12-, 14-, and 17 -membered alkenes in moderate to good yields, while compounds having the sa me groups substituted at their meta positions and those having vinylphenyl groups substituted at their ortho positions afforded mainly polymers. o-All ylphenyl 5-hexenyl ether produced 10-membered cyclooxadecadiene in 7.5% yie ld.
