A process comprising a) contacting (i) ethylene, (ii) a catalyst system comprising 1) a heteroatomic ligand iron salt complex, or a heteroatomic ligand and an iron salt, (iii) hydrogen, and (iv) optionally an organic reaction medium; and b) forming an oligomer product wherein 1) the oligomer product has a Schulz-Flory K value from 0.4 to 0.8 and 2) the oligomer product comprises (a) less than 1 wt. % of polymer, (b) less than 1 wt. % compounds having greater than 70 carbon atoms, (c) less than 1 wt. % compounds having a weight average molecular weight of greater than 1000 g/mol, or (d) any combination thereof wherein the weight percentage is based on the total weight of the oligomer product.

Ethylene oligomerization processes

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.
