METHOD FOR MANUFACTURING PYRIDINE AND PYRIDINE DERIVATIVES FROM ALKYNES AND CYANO COMPOUNDS IN THE PRESENCE OF COMPLEX COBALT OR RHODIUM COMPOUNDS WITH LIGANDS CONTAINING BORON

摘要

The preparation of pyridine and pyridine derivatives from alkynes and cyano compounds including HCN is disclosed. The process can be carried out in the presence of a cobalt or rhodium catalyst having at least one ligand with one or more boron atoms. Certain new cobalt or rhodium catalysts containing such ligand are also disclosed. Also disclosed is a process for the formation of 2-aminopyridine by contacting acetylene with cyanamide such as in the presence of a cobalt or rhodium catalyst which has at least one ligand with one or more boron atoms.
