An unexpected synthetic approach to polysubstituted olefins through the scandium(III) trifluoromethanesulfonate catalyzed ring-opening reaction of donor–acceptor cyclopropanes with 1,1-diphenylethanols was developed. The reactions, which are experimentally easy to handle, feature tolerance of various functional groups and mild reaction conditions. On the basis of experimental evidence, a plausible mechanism was also proposed.

Rhodium complexes ([Rh(COD)(NHC)Cl]) were synthesized by the reaction of bis(1,3-dialkylperhydrobenzimidazolin-2-ylidene) with [RhClCOD]2 in toluene and characterized by elemental analysis, 1H NMR, 13C NMR and IR spectroscopy. These complexes were used as catalysts for the addition of sodium tetraphenylborate to aromatic ketones and corresponding tertiary alcohols were obtained in good yields.

All in one pot: A general synthetic platform allows the interconversion of alcohols and carbonyl compounds in a predictable and controlled fashion in one pot. Under the action of a Ni catalyst, PhCl, CsF, and arylboronates, several multistep alcohol-carbonyl interconversions have been achieved with good overall efficiency (see scheme). A one-pot nickel-catalyzed synthesis of flumecinol (a hepatic microsomal enzyme inducer) has also been demonstrated. Copyright
