Recycling studies were performed by the isolation of the
catalytic material after the first catalytic reaction, however after
the first reaction the catalytic activity was observed to be
reduced suggesting lower stability of the colloids under the
catalytic conditions.
In conclusion, we present a highly efficient protocol for oxidative
esterification of benzyl alcohol with a vast substrate scope.
Although, one cannot overlook the fact that the oxidant used is
expensive and protocols with cheaper metals like Co[79] as well
with expensive metals like Pd[32] which use oxygen as oxidant
exist, the protocol presented here is mild, straightforward and
catalyst is easy to prepare. Other heterobimetallic catalytic
systems are also know involving Pd with noble metals such as
Ag, Au etc. but the selectivity obtained in the protocol presented
in this manuscript is more convenient given the broad substrate
scope presented herein.80 We not only show traditional methyl
esterification of benzyl alcohols but also show unprecedented
transition metal catalysed oxidative esterification of benzyl
alcohol with a variety of complex primary aliphatic alcohols with
long chains, unsaturation, bridged and chiral carbons. We also
characterize the mixed species of heterobi-metallic system of Pd
and Ag with HR-TEM, XRD and XPS. We can suggest presence
of synergism between two metals involved as well as presence
of a probable true hetero bi-metallic system.
