“…A plausible mechanism has been proposed (Scheme 28). This reaction most likely involves an initial cross-coupling bisallene intermediate 92, 36 followed by the formation of cupracyclopentane intermediate 93 and reductive elimination to give the cyclobutane product. The high regioselectivity of the reaction could be explained in terms of the regioselective formation of cupracyclopentane, which would be controlled by the electronic and steric effects of the substitution patterns of bisallene.…”

“…Allenes, bearing two orthogonal cumulative carbon-carbon double bonds, have been applied into a wide variety of annulations [18][19][20][21][22][23][24][25]. Various noble second-and third-row transition metals such as Pd [26][27][28][29][30][31][32], Ir [33], Rh [34][35][36][37][38][39][40] and Ru [41], have been employed for the preparation of cyclic scaffolds from simple, nonfunctionalized acyclic starting materials.…”
