An efficient N-heterocyclic carbene (NHC)-mediated oxidative esterification of aldehydes has been achieved in an undivided microfluidic electrolysis cell at ambient temperature. Productivities of up to 4.3 g h-1 in a single pass are demonstrated, with excellent yields and conversions for 19 examples presented. Notably, the oxidative acylation reactions were shown to proceed with a 1:1 stoichiometry of aldehyde and alcohol (for primary alcohols), with remarkably short residence times in the electrolysis cell (13 s), and without added electrolyte.

Catechol ligands bearing ester groups in 3-position (1a,b, 2) are building blocks for the formation of triply lithium-bridged dinuclear helicate-type complexes [Li1a,b,2)i-. Attachment of appropriate functionalities at the ester unit allows the fine tuning of the polarity of the compounds to afford solubility in highly nonpolar as well as highly polar solvents. The investigations show that the internal dinuclear core is stable in a broad variety of solvents, even in water. Georg Thieme Verlag Stuttgart ? New York.
