Deep eutectic solvent (DES) was employed as dual solvent/catalyst in the green synthesis of α-diazocarbonyl compounds using aldol-type coupling. α-Diazocarbonyl compounds are important syntheticintermediates with useful application for synthesis of amino alcohols and acids and many natural products. Moreover, the method is environmentally friendly because of avoidance of toxic solvents or hazardous

When β-trimethylsiloxy α-diazocarbonyl compounds were treated with trimethylsilyl halide, a mixture of α- and γ-halide substituted unsaturated carbonyl compounds was obtained. The mechanism of this novel diazo decomposition process is discussed.
