Provided is a highly efficient method for the production of aldehydes and ketones, which is inexpensive, exhibits high reactivity, and is capable of easy separation of byproduct after the reaction. More particularly, there is provided a method for producing an aldehyde or a ketone, comprising at least an oxidation step of oxidizing a primary alcohol or a secondary alcohol in the presence of a polymeric carbodiimide represented by the following formula (1) and having a weight-average molecular weight of 300 to 5000, and a sulfoxide compound, together with an acid and a base, or together with a salt of the acid and the base.

Lewis acid. Using these reagents, Lewis acid catalyzed reactions can be run under aprotic conditions, even when acidic protons are produced in the reaction. The use of these reagents for Lewis acid catalyzed ene, Diels-Alder and cycloaddition reactions and Claisenrearrangements is described. These reagents are also useful initiators for cation-olefin addition reactions. In some cases the alkyl groups react
