Abstrakt: 1.During thermal (? 230‡C) and p-toluenesulfonic acid-catalyzed (60–98‡C) cleavage of 4,4'-bis(1-acetoxyethyl)diphenyl ether, a mixture of 4-vinyl-4'-(1-acetoxyethyl)diphenyl and 4,4'-divinyldiphenyl ethers and the products of their oligomerization were formed.2.Thermolysis of 4,4'-bis(1-acetoxyethyl)diphenyl ether at 220–240‡C had an autocatalytic nature, due to the abstracted AcOH. During catalytic cleavage of 4,4'-bis(1-acetoxyethyl)diphenyl ether, AcOH decreased the reaction rate.
