ABSTRACT:
A process for the preparation of .alpha.-methylsubstituted ketones by reacting the corresponding non-methylsubstituted ketones with formaldehyde under hydrogenating conditions. The reaction proceeds easily and with good yields if a catalyst containing metallic palladium deposited on a zirconium, hafnium, titanium or tin phosphate is used. The products are valuable intermediates for the preparation of dyes, crop protection agents or drugs.
