Ruthenium-Catalyzed Dehydrogenation Through an Intermolecular Hydrogen Atom Transfer Mechanism

The direct dehydrogenation of alkanes is among the most efficient ways to access valuable alkene products. Although several catalysts have been designed to promote this transformation, they have unfortunately found limited applications in fine chemical synthesis. Here, we report a conceptually novel strategy for the catalytic, intermolecular dehydrogenation of alkanes using a ruthenium catalyst. The combination of a redox-active ligand and a sterically hindered aryl radical intermediate has unleashed this novel strategy. Importantly, mechanistic investigations have been performed to provide a conceptual framework for the further development of this new catalytic dehydrogenation system.

(ALKYLPHENYL)ALKYLCYCLOHEXANE AND METHOD FOR PRODUCING (ALKYLPHENYL)ALKYLCYCLOHEXANE OR ALKYLBIPHENYL

Disclosed is a method for producing an (alkylphenyl)alkylcyclohexane comprising a step wherein an alkylbenzene and an alkylcyclohexene or alkylcyclohexanol are condensed in the presence of an acid catalyst. Also disclosed is an (alkylphenyl)alkylcyclohexane represented by the formula (8) below. An (alkylphenyl)alkylcyclohexane obtained by such a production method is converted into an alkylbiphenyl, a biphenylpolycarboxylic acid or a biphenylpolycarboxylic acid anhydride. This production method enables to easily and selectively obtain an (alkylphenyl)alkylcyclohexane and an alkylbiphenyl. (8) (In the formula, R1-4 represent an alkyl group having 1-4 carbon atoms, m represents an integer of 0-2, n' represents an integer of 2-5, and the other conditions are as defined in claim 18.)
