Typical example: (3-Formylpropyl)benzoate 2c (19.2 g, 0.1 mol) was mixed with methyl acrylate 3 (13 g; 14 mL; 0.15 mol). After addition of DABCO (1.6 g, 0.015 mol) the resulting homogeneous mixture was allowed to stand at room temperature until 2c was no longer detectable (cu. 7 days). The remaining
