Abstract
An exhaustive kinetic
analysis has been carried out to offer the
convincing evidence of the involvement of the oil–water interface
in guiding “on water organic reaction” mechanism. We
have tuned the interface to prove its indispensable efficacy to make
on water reaction a unique type among water mediated organic reactions.
Sensitive techniques have established the preferential solvation of
polarizable ions at the water surface. The experimental methods have
been developed to control the molecular structure of oil–water
interface in situ. Temperature-dependent analyses have also been presented
to understand the enthalpic and entropic modifications of the interfacial
water molecules during a heterogeneous reaction. Both of our kinetic
and thermodynamic outcomes have univocally established that the hydrogen-bonding
ability of the surface water molecules plays a critical role in deciding
the on water organic reaction mechanism. The results have important
implications on understanding the role of small water molecules adjacent
to the reactants during the reactions discussed in this investigation
