The Synthesis was not completed. The second step did not work, more correct no reaction took place. We thought that changing the conditions of the reaction could lead to a positive outcome. Another way to improve the results could be a new approach as whole. Because of the alken as by-product, the yield was alway very small. If one did choose the alken as product, targeting it with an S-Nucleophilic, the yield could be improved. The drying of the Azid-Donor is also critical, as the donor decomposes in vacuo and under heat. As it’s a non-explosive and air-stable salt, maybe drying it in a desiccator could be a solution. Nonetheless, the Donor is instabel as long it’s not completely dry and must be handled with care.
