A series of air‐stable, nitrile‐ligated (cyclopentadienone)iron dicarbonyl compounds was synthesized and their activities as catalysts in the transfer reduction of acetophenone were explored. While all were active catalysts, the acetonitrile adduct was chosen for further study and was found to be active in the transfer reduction of aldehydes and ketones and in the Oppenauer‐type oxidation of secondary

An object of the present invention is to provide an azo compound capable of improving the dispersibility of an azo pigment in a non-water-soluble solvent. The object of the present invention is achieved with an azo compound wherein a coloring matter moiety having a diketone azo structure and a polymer are bonded to each other.
This application relates to derivatives of hydrocarbon terpenes (e.g., myrcene or farnesene), to methods of making the derivatives, and to the use of the derivatives as surfactants.

We established that a cationic rhodium(I)/dppf or dppb complexcatalyzes a regio- and diastereoselective intermolecular [4+2] carbocyclization of 5-trimethylsilyl-4-pentynals with electron-deficient alkenes leading to cyclohexanones. We also established that a cationic rhodium(I)/(R,R)-Walphos complexcatalyzes a regio- and enantioselective intermolecular [4+2] carbocyclization of 5-substituted 4-pentynals
