3-Formyl-5,6-dihydro-2H-pyran is prepared by conversion of acrolein in the presence of water, acids and halohydrocarbons of 1 to 6 carbon atoms and 1 to 6 halogen atoms as solvents at from 60.degree. to 150.degree. C. The 3-formyl-5,6-dihydro-2H-pyran obtained by the novel process is a valuable starting material for the preparation of dyes and crop protection agents.

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.
