    • General procedure for 2a,b: To a stirred solution of the corresponding aldehyde 3a,b (0.51 mmol) and 2-amino-1,1,3-tricyanopropene (1) (0.76 mmol) in 10 mL of absolute ethanol was added one drop of piperidine/ethanol (1:1). The mixture was refluxed under argon with exclusion of light for 2.5-5 h (TLC monitoring). After cooling, the resulting solid was isolated by filtration, washed with cold ethanol and pentane and dried. Compound 2a: Purple solid (80 mg; 55%). Compound 2b: Violet solid (80 mg; 51%).
