Organomanganese reagents alkylation

Copper-Catalyzed Alkylation of Organomanganese Reagents Preparation of 2,2-Dimethyldecane from tert-Butyl Manganese Chloride. [Pg.267]

Alkylation of organomanganese reagents with alkyl bromides can also be improved by addition of CuCI (3 mol%). The reactions proceed at room temperature and are complete within a few hours [123, 130], The opening of epoxides is also improved under these conditions. The reaction also features good chemoselectivity, tolerating the presence of sensitive functions such as ketones (Scheme 2.59) [130]. [Pg.71]

A useM review on organomanganese reagents in organic synthesis has appeared. As described therein, one of the most stable alkyl Mn(II) reagents is trialkyl manganate, MnRs, which can be conveniently prepared as the Li+ or MgBr+ salt and used at 0 °C. These have been utilized for a variety of reactions, such as the stereoselective alkylation of gew-dibromocyclopropanes (Scheme 2), the silylation of acetylenes, and the radical cyclization of allylic ethers. Some of these transformations can be made catalytic. ... [Pg.2521]
