Abstract

The development of palladium carbene catalysts for telomerization reactions of 1,3-butadiene with alcohols to give alkyl octadienyl ethers was presented. Unprecedented catalyst efficiency with turnover numbers (TON) up to 1,500,000 and turnover frequencies (TOF) up to 100,000/hr were obtained after optimization for the reaction of methanol in the presence of an excess of in situ generated carbene ligands. High yields (75-97%) and catalyst productivities (TON = 15,000-100,000) were observed for other aliphatic alcohols and phenols. For comparison, different (carbene)palladium(0) complexes were synthesized and characterized by X-ray crystallography. Both the electronic and steric effects on the stability and reactivity of the catalysts are discussed also on the basis of density functional theory calculations. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
