Photocatalytic Splitting of CS2 to S8 and a Carbon–Sulfur Polymer Catalyzed by a Bimetallic Ruthenium(II) Compound with a Tertiary Amine Binding Site: Toward Photocatalytic Splitting of CO2?
摘要:
The catalytic photocleavage of CS2 to S-8 and a (CxSy)(n) polymer with visible light using a dinuclear ruthenium(II) compound with a bipyridine units for photoactivity and a vicinal tertiary amine binding site for CS2 activation was studied. The catalyst was characterized by X-ray diffraction, H-1 NMR, and C-13 NMR, ESI-MS and elemental analysis. CS2 photocleavage was significant (240 turnovers, 20 h) to yield isolable S-8 and a (CxSy)(n) polymer. A mononuclear catalyst or one without an amine binding site showed significantly less activity. XPS of the (CxSy)(n) polymer showed a carbon/sulfur ratio similar to 1.5-1.6 indicating that in part both C-S bonds of CS2 had been cleaved. Catalyst was also included within the polymer. The absence of peaks in the H-1 NMR verified the (CxSy)(n) nature of the polymer, while C-13 NMR and IR indicated that the polymer had multiple types of C-S and C-C bonds.
A highly effective hydroxylation reaction of arylhalides with water under synergistic organophotoredox and nickel catalysis is reported. The OH group of the resulting phenols originates from water, following deprotonation facilitated by an intramolecular base group on the ligand. Significantly, aryl bromides as well as less reactive aryl chlorides served as effective substrates to afford phenols with
