Synthesis and spectroscopic studies of some substituted 3-benzoylpyrroles and their tricarbonylchromium complexes

Gogan, Niall J.,McDonald, Robert,Anderson, Hugh J.,Loader, Charles E.

, p. 433 - 436 (2007/10/02)

3-Benzoylpyrroles with a substituent on the pyrrole ring have been synthesized.Both the iodination and chlorination gave only the 2,4 derivatives while isopropylation gave mixtures of the 2,4 and 2,3 compounds.No 3,4 compounds were obtained.Both steric an
