Intrazeolite metal carbonyl kinetics: 12CO substitution in Mo(12CO)6-Na56Y by PMe3 and 13CO
Abstract
The first kinetic study is reported for archetypical substitution reactions of PMe3 and 13CO with the well defined intrazeolite system, Mo(12CO)6-Na56Y, for which excellent isosbestic points and first order behaviour are obtained, the activation parameters indicate a highly ordered ‘supramolecular’ transition state consisting of activated Mo(12CO)6 and PMe3 or 13CO all anchored to the Na+ ions in the α-cage of the host lattice.
