The first example of cobalt-rhodium heterobimetallic nanoparticle-catalyzed synthesis of alkenyl amides from alkynes, amines, and carbonmonoxide is described.
A novel carbonylative decomplexation of alkyne-dicobalt hexacarbonyls, i.e. hydrocarbamoylation of alkynes, was carried out by reaction of the complexes with 10 equiv. of primary and secondary amines.
