PROCESS FOR THE DIRECT CONVERSION OF LACTONES INTO UNSATURATED KETONES OR ALDEHYDES

The present invention refers to a process for the preparation of unsaturated ketones or aldehydes by pyrolysis of a lactone, in the presence of a reducing agent such as molecular hydrogen or a carboxylic acid, and in the presence of a catalyst, optionally

Unsymmetrical unsaturated ketones from lactones and carboxylic acids in one step

A one-step transformation of γ- and δ-(spiro)lactones into γ,δ- and δ,ε-unsaturated ketones in the presence of carboxylic acids in the vapor phase at 400° over a supported manganese catalyst is reported for the first time. The scope of this new transformation is exemplified with a series of lactones, and a mechanistic rationale is proposed.
