Chiral biphenols catalyze the enantioselective asymmetric propargylation of ketones using allenylboronates. The reaction uses 10 mol % of 3,3′-Br2-BINOL as the catalyst and allenyldioxoborolane as the nucleophile, in the absence of solvent, and

Alkyl groups in trialkylboranes were successfully transferred to carbonyl compounds in the presence of the platinum cathode and copper anode by electrochemical method. The new, mild electrochemical alkyl transfer reaction produced various substituted alcohols in good yields.
Generation and Reactivities of Organocerium Reagents

Organocerium reagents, prepared in situ by the treatment of organolithium compounds with cerium(III) iodide, exhibit characteristic reactivities toward ketones; at -65 deg C, nucleophilic additions give the corresponding tertiary alcohols in excellent yields; while, at 0 deg C to ca. room temperature, reductive coupling and/or reduction of the ketones prevail.
