Vinylmagnesium bromide-copper iodide

Trimethy lsilyl)vinylmagnesium Bromide-Copper(I) Iodide ... [Pg.730]

The conjugate addition of trimethylaluminium to pulegone in the presence of nickel acetylacetonate232 and the conjugate addition of vinylmagnesium bromide in the presence of copper iodide and isopropyl sulphide have been described.233... [Pg.31]

A number of examples for the copper-catalyzed carbometallation151,300,300a or stannylmetallation61,61a of G-G double or triple bonds have been described in recent years. For example, reaction of ethynyl carbamate 346 with n-butylmagnesium bromide in the presence of 10 mol.% of copper(i)-iodide induced a smooth regio- and stereoselective carbomagnesiation to afford the vinylmagnesium intermediate 347 which can be trapped with benzaldehyde to the allyl alcohol 348 (Scheme 97).151... [Pg.551]
