39. Nevertheless, our preliminary investigation indicated that 19% GC yield of 7 was detected only in the presence of a catalytic amount of CuI although the formation of diyne side product predominantly occurred (Scheme 1, eq 1). Further efforts for the clarification of the role of CuI are ongoing.
