“…While he does not say so specifically, Semmler (665) probably used sodium and alcohol to reduce /3-acetoxystyrene to /3-phenethyl alcohol. With sodium and alcohol /3-phenoxystyrene gave a 65 per cent yield of ethylbenzene (710).…”

“…The compound also was prepared in [40][41][42][43][44][45][46][47][48][49][50] per cent yield by treating p-ethylphenol with a large excess of bromine, by brominating the ethyltribromophenol, and by adding hydrogen bromide to the quinoid and normal forms of the corresponding ß-bromostyrene. -Ethoxystyrene reacted instantly with bromine (508), and an unstable dibromide was obtained from ß-phenoxystyrene (710). Treatment of a-phenoxystyrene with bromine gave only tar (635).…”

“…Under the same conditions m-methylstyrene dibromide gave m-methyl-a-bromostyrene (525). On heating at reduced pressure /3-phenoxystyrene dibromide also lost hydrogen bromide, giving a compound postulated as /3-bromo-/3-phenoxystyrene (710).…”

“…C6H6COC=CHC6H6 + KOH -^L> C6H6CH==CHOC2H5 + C6H6COOK OC2H6 Pyrolysis (260°C.) of -phenoxycinnamic acid gave 13-14 per cent of phenyl phenylacetate and the remainder of the product was /3-phenoxystyrene (710).…”

“…/3-Phenoxystyrene reacted with ethyl alcohol in the presence of potassium hydroxide at 200°C. to give /3-ethoxystyrene and a little styrene (710). /3-Methoxystyrene has been postulated as an intermediate in the preparation of phenylacetaldehyde by treating styrene iodohydrin methyl ether with silver nitrate (741).…”
