Abstract
Substituted-ethenyl alkyl ethers of formula <FORM:0897685/IV (b)/1> where R and R2 represent a C1-8 alkyl radical and R1 a hydrogen or a C1-8 alkyl radical, are prepared by heating a mixture of a ketal <FORM:0897685/IV (b)/2> with an alkali-metal bisulphate or with acetic anhydride and pyridine. Examples describe the preparation of 2-ethoxy-buten-(2) from 2,2-diethoxybutane, 3-ethoxy-penten-(3) from 3,3-diethoxy pentane, 2-ethoxy-propen-(1) from 2,2, diethoxypropane, 2-ethoxy-4-methyl-penten-(2) from 2,2-diethoxy-4-methyl-pentane. Ketals of the above type are prepared by reacting the ketone with orthoformic ester and boron trifluoride etherate.
