Abstract
Methods for the photocatalytic reduction of alkynes to alkenes with high conversion yields and selectivities using a heterogeneous system that incorporates a cobalt-porphyrin into a metal-organic framework (MOF) are provided. The cobalt-porphyrin-based MOFs carry out the photocatalytic reductions in the presence of a visible-light activated photosensitizer molecule and a sacrificial electron donor.
Claims20
A method for photocatalytic reduction of an alkyne to an alkene, the method comprising:
- exposing the alkyne to a solution comprising:
- a metal-organic framework comprising inorganic metal ions or clusters connected by polytopic organic linkers, the polytopic organic linkers comprising cobalt-porphyrin groups;
- a photosensitizer;
- and a sacrificial donor;
- and
- irradiating the photosensitizer with visible radiation to induce the photocatalytic reduction of the alkyne to the alkene.
