thesis contains two parts.In the first part, general and versatile palladium-mediated11C-Cbond forming reactions for use in the production of radiotracers for Positron Emission Tomography (PET) were explored. Two complimentarty approaches were investigated: the coupling of [11C]methyliodide with a vinyl stannane and the reaction of a [11C]methylated stannane with various organohalides. The former approach

A series of hollow fiber membranes containing immobilized enzymes were prepared and used in the synthesis of 11C-labelled nucleosides. 11C-Formaldehyde was produced in an alcohol oxidase/catalase bioreactor and circulated through a thymidylate synthase bioreactor with an appropriate substrate to produce the corresponding 11C-nucleotide. These labelled nucleotides were subsequently dephosphorylated in an alkaline phosphatase bioreactor. The bioreactor approach was amenable to hot-cell conditions and yielded 11C-products in higher yield and shorter synthesis times than conventional chemical approaches.
