ABSTRACT:
A method for producing an aromatic carbonyl compound represented by the formula (B)-1 or (B)-2: ##STR1## comprising decomposing a hydroperoxide represented by the formula (A)-1 or (A)-2: ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are defined in the specification, in an inert gas atmosphere in the presence of an aqueous layer containing an iron salt, a copper salt and an acid is disclosed. Novel m-(2-hydroxy-2-propyl)acetophenone and m-isopropenylacetophenone which are useful as an intermediate for the preparation of medicines are also disclosed. A method for producing m-isopropenylacetophenone comprising dehydrating m-(2-hydroxy-2-propyl)acetophenone in the presence of an acid catalyst is further disclosed.
