title: Heterogeneous reductive isomerization reaction using catalytic Pd/C and H2.
abstract: [reaction: see text] A highly selective catalytic reductive isomerization reaction is described. The extremely mild and neutral reaction conditions (10% Pd/C, H2, and MeOH at 0 degrees C) tolerate a wide range of functional groups and generally result in excellent yields. Mechanistic studies suggest that this reaction does not proceed via a stepwise reduction/elimination sequence or a pi-allylpalladium intermediate.
