Abstract

The [Pd(SIPr)(PCy3)] complex efficiently
promotes a tandem process involving dehydrogenation of
formic acid and hydrogenation of C−C multiple bonds
using H2 formed in situ. The isolation of a key catalytic
hydridoformatopalladium species, [Pd{OC(O)H}(H)-
(IPr)(PCy3)], is reported. The complex plays a key role
in the Pd(0)-mediated formation of hydrogen from formic
acid. Mechanistic and computational studies delineate the
operational role of the palladium complex in this efficient
tandem sequence.
