ORGANO CYANOCUPRATES. II. REACTIONS AVEC LES CETONES α-HALOGENEES
Hamon, Louis,Levisalles, Jacques
, p. 259 - 272 (1983)
Comparison of lithium dimethylcuprate versus methylcyanocuprate as nucleophilic methylating reagents for α-halo ketones shows better selectivity for alkylation in the case of methylcyanocuprate, especially in the mixed solvent ether/dimethylformamide.The inverse addition techniques and addition of ligands such as dimethyl maleate also improve the selectivity.Methylcopper in the presence of chelating agents gives good selectivity but the reaction is slower.

Indolyl fragment containing phenanthroline based new ligands and their corresponding Ru(ii) complexes were synthesized and fully characterized by various spectroscopic techniques. The catalytic activity of these newly synthesized cyclometalated (NNC)Ru(ii) complexes was explored towards the β-methylation of alcohols using methanol. Notably, these complexes displayed superior reactivity compared to various (NNN)Ru(ii) complexes. Utilizing this strategy, a wide range of primary, secondary, and aliphatic straight chain alcohols were selectively methylated. This protocol was further employed for the methylation of a few natural products and the gram scale synthesis of β-methylated alcohols. A series of control experiments and kinetic studies were performed to understand the plausible reaction mechanism.
Nickel-Catalyzed Ring-Opening Allylation of Cyclopropanols via Homoenolate

We report herein a nickel-catalyzed ring-opening allylation of cyclopropanols with allylic carbonates that occurs under mild and neutral conditions. The reaction displays linear selectivity for both linear and branched acyclic allylic carbonates and is also applicable to cyclic allylic carbonates, affording a variety of δ,?-unsaturated ketones in moderate to good yields. Mechanistic experiments are in accord with a catalytic cycle involving decarboxylative oxidative addition of allylic carbonate to Ni(0), alkoxide exchange with cyclopropanol, cyclopropoxide-to-homoenolate conversion on Ni(II), and C-C reductive elimination.
