Abstract: Compounds and processes for catalytic ring-opening cyclooligomerization metathesis and ring-closing metathesis of olefins are described. The compound is a molybdenum or tungsten metal (M) complex which comprises an imido ligand (N—R) bound to the M to provide an M=N—R site, an M=C reaction site wherein the C of the M=C reaction site is tethered to the R of the imido ligand via a carbon or carbon and heteroatom (NOS) chain containing 1 to 12 carbon atoms to form a ring structure, and two to four ligands (R?) bound to the M to provide two to four M-R? sites. In particular embodiments, the M-R? sites include each of the oxygens of a dialkoxide ligand or each of the nitrogens of an ?1-pyrrolyl ligand bound to the M.

Abstract: A process is described for producing one or more substituted iminoamines, in particular ?-unsaturated ?-iminoamines, in a single reaction comprising reacting one or more primary amines, alkynes, and isonitriles in the presence of a transition metal catalytic complex, preferably a titanium metal catalytic complex such as (N,N-di(pyrrolyl-?-methyl)-N-methylamine)titanium (Ti(NMe2)2(dpma)), under reaction conditions effective for 3-component coupling of the primary amines, alkynes, and isonitriles to produce one or more of the substituted iminoamines.
