The use of cobaltârhodium (Co2Rh2) heterobimetallic nanoparticles in the cyclohydrocarbonylation of substituted alkynes and tandem cyclohydrocarbonylationâCO insertion of α-keto alkynes to give 2(3H)- or 2(5H)-furanones is described.
Process for preparing 2,2-difluoroethylamine derivatives, wherein compounds of the general formula (IV) are reduced to the corresponding 2,2-difluoroethylamine derivatives of the general formula (III), where the A radical is as defined in the description:
