The present invention discloses processes for producing substituted pyrrole compounds, such as 2,5-disubstituted pyrroles. Synthetic processes which directly convert substituted furan compounds to substituted pyrrole compounds, via a reaction of the substituted furan compound with ammonia and/or an ammonium salt in the presence of a catalyst, also are described. 1. (canceled)3. The process of claim 2 , wherein R claim 2 , R claim 2 , R claim 2 , and Rindependently are a hydrogen atom or a C-Chydrocarbyl group claim 2 , and{'sup': 2p', '3p', '4p', '5p, 'at least one of R, R, R, and Ris not a hydrogen atom.'}4. The process of claim 2 , wherein Rand Rindependently are a C-Chydrocarbyl group claim 2 , and Rand Rare hydrogen.5. The process of claim 2 , wherein Rand Rindependently are a methyl group claim 2 , an ethyl group claim 2 , an n-propyl group claim 2 , an iso-propyl group claim 2 , an n-butyl group claim 2 , a t-butyl group claim 2 , a phenyl group claim 2 , a benzyl group claim 2 , a tolyl group claim 2 , or a xylyl group.6. The process of claim 2 , wherein at least one of Rand Ris a hydrogen atom.8. The process of claim 24 , wherein the substituted pyrrole compound comprises 2 claim 24 ,5-dimethylpyrrole claim 24 , 2-methyl-5-ethylpyrrole claim 24 , 2 claim 24 ,5-diethylpyrrole claim 24 , 2-ethyl-5-methylpyrrole claim 24 , 2-ethyl-5-n-propylpyrrole claim 24 , 2 claim 24 ,5-di-n-propylpyrrole claim 24 , 2 claim 24 ,5-diisopropylpyrrole claim 24 , 2 claim 24 ,5-di-n-butylpyrrole claim 24 , 2 claim 24 ,5-di-n-pentylpyrrole claim 24 , 2 claim 24 ,5-di-n-hexylpyrrole claim 24 , 2 claim 24 ,5-di-n-heptylpyrrole claim 24 , 2 claim 24 ,5-di-n-octylpyrrole claim 24 , 2 claim 24 ,3 claim 24 ,5-triethylpyrrole claim 24 , 2 claim 24 ,3 claim 24 ,5-tri-n-butylpyrrole claim 24 , 2 claim 24 ,3 claim 24 ,5-tri-n-pentylpyrrole claim 24 , 2 claim 24 ,3 claim 24 ,5-tri-n-hexylpyrrole claim 24 , 2 claim 24 ,3 claim 24 ,5-tri-n-heptylpyrrole claim 24 , 2 claim 24 ,3 claim 24 ,5-tri ...
