Lewis does it better : Aluminum triflate readily replaces Brønsted acid cocatalysts in the palladium‐catalyzed methoxycarbonylation reaction of styrene and 1‐pentene, producing catalysts that are stable and more active than those using traditional acids. Catalyst loadings of 0.02 % allow conversions of up to 100 % to be achieved within three hours with no loss of linear/branched ester selectivity.
