Catalysis and destabilization strategies for the hydrogenation and dehydrogenation of boron/nitrogen systems

Department Name: Oxford Chemistry

Abstract

The primary objective of this proposal is the development of novel chemistry/catalysis to optimize the kinetics and extent of dihydrogen evolution from ammonia borane (AB). AB represents a very promising hydrogen storage material (19.6 wt % hydrogen), the exploitation of which will be significantly advanced by the application of two complementary approaches, based around either stoichiometric or catalytic exploitation of metal reagents: (i) chemical modification designed to disrupt the framework of dihydrogen bonding in the solid state and thereby facilitate more facile and complete evolution of H2; and (ii) transition metal catalysis of AB dehydrogenation, focussing in particular on the elucidation of mechanistic information, thereby allowing for the rational design of more efficient catalyst systems.
 
Description Reactions of saturated and unsaturated organic molecules with boron-containing reagents represent a very powerful
and versatile range of methodologies for the introduction of functionality into organic substrates, which have been widely
exploited, e.g. in the syntheses of pharmaceuticals, natural products and functional materials. this research has developed new methodologies for carrying out the synthesis of these key intermediates
Exploitation Route Initially through academic dissemination and use of methodologies by others in synthesis; in the medium term - within fine chemical synthesis
Sectors Chemicals
