METHOD FOR PRODUCING PYRIDINE AND PYRIDINE DERIVATIVES FROM ALKINES AND CYANO COMPOUNDS IN THE PRESENCE OF COBALT OR RHODIUM COMPLEX COMPOUNDS WITH BORUS LIGANDS

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.
