Ligands for use with catalyst compositions used in hydroformylation reactions are described herein. The ligands are used with various octofluorotoluene or hydrocarbon solvents and achieve an increase in isoselectivity with an increase in temperature, an increase in TON with an increase in temperature, and/or will show isoselectivity that is surprisingly high in comparison to the hydroformylation reactions using common solvents.

Also, processes for the preparation of the complexes, and their use in carbon-carbon and carbon-heteroatom coupling reactions.

The disclosure is directed to: (a) phosphacycle ligands; (b) catalyst compositions comprising phosphacycle ligands; and (c) methods of using such phosphacycle ligands and catalyst compositions in bond forming reactions.

The present disclosure discloses a photocatalyst for hydrogen production from water. The photocatalyst comprises triphenylphosphine ruthenium (RuP) complex. The RuP complex is a co-catalyst with graphitic carbon nitride. The present disclosure also discloses a method of synthesizing a photocatalyst for hydrogen production from water. The method comprises forming a suspension of graphitic carbon nitride; adding triphenylphosphine ruthenium complex (RuP) to the suspension; and drying the suspension to form dried graphitic carbon nitride integrated with RuP.
