Applying Tethered N-Heterocyclic Stannylene Ligands in Catalysis
Lead Research Organisation:
Heriot-Watt University
Department Name: Sch of Engineering and Physical Science
Abstract
This is a PhD research project in Chemistry. C-H activation, i.e. the cleavage of a usually inert C-H bond at a metal centre, has attracted great interest in recent years as it is a key initial step in the use of simple hydrocarbons as feedstocks for catalysis. Building on new tethered ligands that have recently been synthesised in the Mansell group, this project in main group and organometallic chemistry will look to exploit the unconventional donor properties of tethered N-heterocyclic stannylenes in catalysis, and compare their properties with their lighter analogues; tethered saturated N-heterocyclic carbenes.

Description | We have discovered a new bimetallic base which been successfully used in our research and has been published. We have discovered a range of new binding modes for Lithium with NHCs. Also we have review the scope of current bimetallic NHC complexes. We have developed a catalyst for C-H activation of arenes and alkanes. |
Exploitation Route | Further grant applications for the continued development of these catalysts is ongoing. A subsequent PhD student is continuing some of the research. |
