Abstract

Acyl alkyl phenols are prepared by dehydrogenating a compound of the formula: <FORM:0951435/C2/1> where R1 represents an alkyl or aryl group, R2 represents a hydrogen atom or an alkyl or aryl group, R3 represents a hydrogen atom or alkyl group and R4 represents an alkyl or aryl group. The dehydrogenation may be carried out by distilling the cyclohexenone in the presence of a dehydrogenation catalyst e.g. a platinum group metal or by halogenating the cyclohexenone with chlorine, bromine or iodine and dehydrohalogenating the reaction product. Examples are given. Specification 852,935 is referred to.
