The flow synthesis of ortho-substituted carboxylicacids, using carbon monoxide gas, has been studied for a number of substrates. The optimised conditions make use of a simple catalyst system compromising of triphenylphosphine as the ligand and palladium acetate as the pre-catalyst. Carbon monoxide was introduced via a reverse "tube-in-tube" flow reactor at elevated pressures to give yields of carboxylated

The bowl-shaped, 3-fold interlinked porphyrindimer 2 was obtained in respectable yields during macrocyclization attempts. Its bicyclic structure, consisting of a macrocycle made of a pair of acetylene interlinked tetraphenylporphyrins which are additionally linked by a C-C bond interlinking two pyrrole subunits, has been confirmed spectroscopically (2D-NMR, UV/vis, HR-MALDI-ToF MS). Late-stage functionalization

generation of the desired trifluoroacetylation products, which was not possible previously due to the exclusive formation of trifluoromethylated oxazoles (vide infra). In the course of this work we succeeded for the first time in isolating and characterizing (HRMS, IR, 1H, 13C and 19F NMR, X-ray) different intermediates of the Dakin–West reaction allowing us to probe its mechanism.

Three Donor–π–Acceptor (D–π–A) type dyes, with triphenylamine (TPA) as electronic donor, enediyne (EDY) moiety as π linker and cyanoacrylic acid as both electronic acceptor and anchoring group, were designed and synthesized. These EDY-bridged dyes with different donor position and number are used as sensitizers in dye-sensitizedsolarcells (DSSCs) to study the influence of these factors on their performance
