Abstract:
Chapter 1 provides an overview of the past developments in the field of syngas conversion. Previously developed heterogeneous and homogeneous catalytic systems for syngas conversion are discussed along with the different mechanisms proposed for these processes. The use of main group and metal hydrides in CO reduction is covered, along with hydrogen activation chemistry and their application for syngas conversion. Step-wise systems for indirect syngas conversion are also described. Chapter 2 describes the synthesis and characterisation of novel transition metal complexes bearing substituted bipyridyl ligands with pendant basic groups. The reactivity of the complexes towards carbon monoxide and hydrogen is also investigated. Chapter 3 describes the synthesis and characterisation of novel transition metal pincer complexes. The reactivity of these complexes with hydrogen and carbon monoxide is reported and the fluxionality of a Ru(II) complex is studied. In Chapter 4, the reduction of carbon monoxide at a metal centre with metal hydride complexes is described, along with in situ hydrogen activation to form the hydride donors. The mechanisms and products of the reactions are investigated, and the implications with regard to syngas conversion discussed. The CO tolerance of novel transition metal complexes in the hydrogenation of carbonyl substrates is also reported. Experimental details relating to the synthesis and characterisation of the novel compounds in Chapters 2 to 4 are detailed in Chapter 5.
