In accordance with this invention, 2,2-diorgano-1-indanones are produced by reacting an alcohol which is the corresponding (diorganosubstitutedmethyl)phenyl(or substitutedphenyl)carbinol, with carbon monoxide in the presence of a Lewis acidcatalyst, with any substituents on the phenyl group of the alcohol being hydroxy or organo.

A method is provided for the production of 2,2-diorgano-1-indanones, e.g., 2,2-dimethyl-1-indanone, by reacting an alcohol which is the corresponding (diorganosubstitutedmethyl)phenyl(or substitutedphenyl)carbinol, e.g., 2-methyl-1-phenyl-1-propanol, with carbon monoxide in the presence of a Lewis acid catalyst, e.g., hydrogen fluoride, with any substituents on the phenyl group of the alcohol being hydroxy or organo. The foregoing reaction is preferably integrated with the preparation of the feed alcohol by reducing the corresponding (diorganosubstitutedmethyl)phenyl(or substitutedphenyl)ketone, e.g., isobutyrophenone, with a reducing agent containing available hydrogen, e.g., sodium borohydride, or with hydrogen gas in the presence of a hydrogenation catalyst.
