## Abstract A new synthesis of β‐hydroxyesters involving a reaction between a carbonyl compound, ketene and an alkyl‐orthotitanate is described. The following carbonyl compounds have been studied: aldehydes, ketones, α‐diketones, α‐ or γ‐ketoesters. A reaction mechanism is proposed.
New aza heterocycles with benzimidazole, pyrazole and pyridine moieties in the same molecule have been prepared. Preliminary complexing properties with divalent copper salts were determined by means of mass spectrometry (FAB) and a very interesting oxydation reaction with molecular oxygen was shown.
