Abstract

0022-3263/84/1949-1119 $01.50/0 reactivity have not been undertaken until recently. 2 Such studies of thermal stability3 have resulted in the development of new heterocuprates (R'= PPh2, NCy,) that have the highest stability and still maintain high reactiv-it^.^ However, in some reactions these new cuprates were still too far away from our goal of a high yield with but 1.0 equiv of R. This is essential if cuprate reactions are to be used to make the key ...
