ON-SURFACE PHOTOCHEMISTRY OF PRE-ORDERED 1-METHYL-2-PHENYL-ACETYLENES: C-H BOND ACTIVATION AND INTERMOLECULAR COUPLING ON HOPG.

In this contribution we report on light-induced metal-free coupling of propynylbenzene molecular units on highly oriented pyrolitic graphite. The reaction occurs with high selectivity within the self-assembled monolayer and leads to the generation of covalently coupled 1,5-hexadiyne derivatives under topological control. Such photochemical uncatalysed pathway represents an original approach in the field of topological C-C coupling at the solid/liquid interface.
