Va. Nikanorov et al., FIRST EXAMPLE OF CARBONYL CONDENSATION OF CYCLOPENTADIENONE HYDRAZONEGIVING MIXED AZINE AND ITS SUBSEQUENT ENDO-DIMERIZATION INTO THE TRICYCLO[5.2.1.0(2.6)]DECADIENE SYSTEM, Russian chemical bulletin, 45(7), 1996, pp. 1667-1669
The monomeric hydrazone of cyclopenta-2,4-dienone (cyclone) undergoes
condensation with 2-hydroxy-3-methoxybenzaldehyde to yield the corresp
onding mixed azine, which spontaneously dimerizes to 4, ybenzalazino)t
ricyclo[5.2.1.0(2.6)]deca-3,8-diene.
