PROCESS FOR THE PREPARATION OF ALPHA-METHYL-SUBSTITUTED CARBONYL COMPOUNDS |
摘要 |
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. |
