Organocopper reactions

This procedure illustrates a general method for the preparation of alkenes from the pal 1 adium(Q)-cata1yzed reaction of vinyl halides with organo-lithium compounds, which can be prepared by various methods, including direct regioselective lithiation of hydrocarbons. The method is simple and has been used to prepare a variety of alkenes stereoselectively. Similar stoichiometric organocopper reactions sometimes proceed in a nonstereoselective... [Pg.45]

Conjugate Addition of Alkyl Groups Organocopper Reactions... [Pg.728]

In spite of the good success achieved in catalytic organocopper reactions, recent developments have emphasized the stoichiometric reagents. Presumably this is due to a greater reproducibility in results, with higher yields and greater stereoselectivity reported.1 31... [Pg.173]

The mechanism(s) of organocopper reactions are by no means settled - . The exchange of equation (207) has been discussed as an oxidative addition followed... [Pg.386]

In general, the feasibility of the reactions depends on the reactivities of substrates and could be interpreted in terms of steric and electronic factors. Initially, in the history of organocopper reactions, substrates were limited to relatively unhindered, 3i,/ -unsaturated ketones and esters. Since the / -substitution to a, -unsaturated carbonyl compound retards... [Pg.594]

Alkenyl triflones The fZ>alkenyl triflones can be made from alkynyl triflones by the addition of HI followed by StUle coupling. Some other alkenyl triflones are available from organocopper reactions. [Pg.4]
