| Research Abstract |
A novel transition-metal-catalyzed addition of organotellurium compounds to unsaturated carbon-carbon bonds, according to an oxidative addition/reductive elimination sequence, has been developed. Carbamotelluroates added intramolecularly to alkynes and allenes in the presence of catalytic Pd(PPh_3)_4 to afford the corresponding lactams. The coordination of the alkyne or allene unit to the metal center in the oxidative adducts and the coordination of the carbonyl oxygen to tellurium in the final products where critical to the success of the reaction.
