Methylaluminum bis(2,6-di-tert-butyl-4-alkylphenoxide). A new reagent for obtaining unusual equatorial and anti-Cram selectivity in carbonyl alkylation
The indium-catalyzed allylation reaction was performed in good yields and short reaction time with various cyclohexanones in water. Aqueous facial amphiphilic carbohydrates solutions were also screened for their potency to modify the stereochemical outcome of the reaction. (C) 2010 Elsevier Ltd. All rights reserved.

The Lewis acid-promoted addition of allyl(cyclopentadienyl)iron(II) dicarbonyl (1) to unactivated ketones provides zwitterionic iron-olefin complexes 5 as isolable salts. Treatment of these complexes with NaI in wet acetone affords homoallylic alcohols in good to excellent overall yields.
