Abstract
A method for preparing polyamide comprising reacting carbon monoxide and the reactant pair ##STR1## wherein --Ar.sup.1 -- and --Ar.sup.2 -- are each independently selected from the group consisting of aromatic and heteroaromatic moieties having a total of ring carbons and heteroatoms of from 6 to about 30, in the presence of solvent and a catalyst. The catalyst is a compound of a metal selected from the group consisting of platinum, palladium and nickel.

A method for preparing polyamide comprising reacting carbon monoxide and the reactant pair ##STR17## wherein --Ar.sup.1 -- and --Ar.sup.2 -- are each independently selected from the group consisting of aromatic and heteroaromatic moieties having a total of ring carbons and heteroatoms of from 6 to about 30, in the presence of solvent and catalyst, said catalyst being selected from the group consisting of platinum compounds, palladium compounds, and nickel compounds.
A method for preparing polyamide comprising reacting carbon monoxide, an aromatic di(trifluoromethane sulfonate having the general formula ##STR22## and an aromatic diamine having the general formula
- H.sub.2 N--Ar.sup.2 --NH.sub.2,
- wherein --Ar.sup.1 -- and --Ar.sup.2 -- are each independently arylene or heteroarylene, each said trifluoromethane sulfonate group is non-ortho, in the presence of solvent and a palladium catalyst having a palladium atom in the zero valent or divalent state.
