There is disclosed a method for producing aromatic polyamides represented by the following formula (III), which comprises reacting an aromatic dihalogen compound represented by the following formula (I) with a diamine compound represented by the following formula (II) in the presence of cobalt/phosphine complex and a basic substance under carbon monoxide atmosphere:

Method for synthesizing aromatic polymers

A catalyst for hydroformylation of an olefin with H.sub.2 and CO is disclosed which includes an inorganic oxide carrier, and two or more catalytic metal components supported on the carrier, the metals of said catalytic metal components being cobalt and at least one auxiliary metal selected from rhodium, ruthenium, rhenium, iridium, platinum, palladium, copper, osmium and gold. By contacting a feed of an olefin, H.sub.2 and CO with the catalyst, the olefin is converted into an aldehyde and an alcohol.

Catalyst for producing aldehyde and alcohol from olefin, carbon monoxide

A process for the preparation of cyclooctene which comprises irradiating 1,5-cyclooctadiene with light in the presence of a photodehydrogenation catalyst, acetone and an alcohol to partially hydrogenate the 1,5-cyclooctadiene.
