The Pd-catalyzed addition of organozinc reagents to unsaturated carbonyls in the presence of carbon monoxide provides 1,4-diketones in good yield. The reaction was studied with a number of substituted cyclic and acyclic ketones as well as α,β-unsaturated aldehydes.

Highly substituted 4-keto-1-nitroalkanes cyclize under basic conditions to dihydro-1,2-oxazine N-oxides.These N-oxides are thermally unstable and decompose to 1,4-diketones.BF3 catalyzes a similar decomposition, but probably via a different mechanism.
