benzil (diketone) and with benzophenones (monoketone) in THF rates of electrontransfer and of successive R• transfer from Grignard reagents were determined by direct observations of intermediate radicals. The electrontransfer rates from Grignard reagents to ketones are dependent on both the electrochemical properties of Grignard reagents and ketones.

Rh(I)/diene-catalyzed additionreactions of arylboroxines/arylboronic acids with unactivated ketones to form tertiary alcohols in good to excellent yields are described. By using C2-symmetric (3aR,6aR)-3,6-diaryl-1,3a,4,6a-tetrahydropentalenes as ligands, the asymmetric version of such an additionreaction, with up to 68% ee, was also realized.

Disclosed herein are a reaction method and a production method of an organic compound which are capable of achieving high reaction selectivity according to the purpose and a high production rate of a target substance. The methods include at least two fluids, wherein at least one kind of the fluids is a fluid containing at least one organic compound and at least one kind of the fluids other than the above fluid is a fluid containing at least one reactant in the form of a liquid or solution, and the respective fluids join together in a thin film fluid foamed between processing surfaces arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, whereby an organic reaction is performed in the thin film fluid.

via three-component coupling between in situ generated 1-lithio bicyclo [1.1.0]butane, a broad variety of ketones, aldehydes and N-tosyl imines, and aryl triflates. The key step involves a highly diastereoselective palladium-catalyzed C−C σ-bond alkoxyarylation (or aminoarylation) of bicyclo [1.1.0]butyl carbinolate intermediates.
