Preparation. The complex is prepared from 2-methallyl bromide and nickel carbonyl in 85% yield by the method of Semmelhack and Helquist (4, 353). Reaction with carbonyl compounds. The complex reacts with aldehydes and ketones to produce homoallylic alcohols ... [Pg.361]

Two recently developed coupling reactions of an alkene (R1CH2CH=CH2), an aldehyde (R2CHO), and a silyl triflate (R33SiOTf) yield an allylic (66) or homoallylic (67) alcohol (in protected form).188 Employing nickel-phosphine catalysts, either product can be selected by small changes in the phosphine component. A mechanism distinct from that of Lewis acid-catalysed carbonyl-ene reactions is proposed and discussed. [Pg.24]
