Product Details of 948552-36-1. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 1H-Pyrazole-5-carbaldehyde, is researched, Molecular C4H4N2O, CAS is 948552-36-1, about Synthesis of pyrrolo[1,2-c]imidazol-5-one, pyrrolo[1,2-a]imidazol-5-one, and pyrrolo[1,2-b]pyrazol-6-one (three isomeric azapyrrolizinones) by pyrolysis of Meldrum’s acid derivatives. Author is McNab, Hamish.
Reaction of Meldrum’s acid with 4- or 2-imidazolecarboxaldehyde or 3-pyrazolecarboxaldehyde gave condensation products, which were pyrolyzed in the gas phase to give the title aza analogs I-III, resp., of 3-pyrrolizinone, as air-sensitive yellow solids.
This compound(1H-Pyrazole-5-carbaldehyde)Product Details of 948552-36-1 was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
