Rhodium-catalyzed diarylation of oxalates using arylboron compounds

Dialkyl oxalates undergo selective diarylation on one of their carbonyl carbons upon treatment with arylboron reagents in the presence of a rhodium catalyst to give the corresponding α-hydroxydiarylacetates. Under similar conditions, the arylation of benzoylformate and benzil also proceeds efficiently.

Ethylene Dications Substituted with Electron-Donating Groups

Direct spectroscopic observations were made of substituted ethylene dications bearing ?-stabilizing groups such as an aryl, a hydroxy, or a methoxy group in a strong acid, trifluoromethanesulfonic acid (TFSA).Based on the spectroscopic evidence, we reached the following conclusions. (1) 1,1-Diaryl-2-hydroxy-2-methoxyethylene dications, 1,1-diaryl-2,2-dihydroxyethylene dications, and 1,1,2-triaryl-2-hydroxyethylene dications are discrete intermediates in the electrocyclization reaction to yield the fluorene and phenanthrol in TFSA. (2) Several dications bearing methoxy substituents on the aromatic rings are formed in trifluoroacetic acid (TFA). (3) NMR spectra suggested the nonplanar structures of O-protonated α-carbonyl diarylmethyl dications at the central C-C bond. (4) 1,2-Diaryl-1,2-dihydroxyethylene dications and 1-aryl-1,2,2-trihydroxyethylene dications are very stable.Ab initio MO calculations showed that 1,2-dihydroxyethylene dications are more stable than 1,1-dihydroxyethylene dications.
