In conclusion, a heterogeneous LDH-Pd0 catalyzed chemoselective
hydrogenation of olefinic double bonds in the presence of
other functional groups at room temperature has been successfully
developed. The solid catalyst easy to handle can be readily recovered
and reused, thus making this procedure more environmentally
acceptable. We believe that this methodology may find widespread
use in organic synthesis for the chemoselective hydrogenation of
double bonds.
