Catalysis multiple attack

The metallacycles can also be used for carbon-carbon bond-forming reactions (Scheme 5.67). Transmet-allation with cuprates, or the use of catalysis by copper(I) salts allows reaction with a variety of electrophiles. With an acid chloride, reaction occurs at one of the carbon-zirconium bonds of the metallacycle 5.234. This leaves the second carbon-zirconium bond of the acylated product 5.235 available for further chemistry by, for instance, halogenation, or back attack onto the ketone. More elaborate multiple component couplings can also be achieved (Scheme 5.68). ... [Pg.178]
