Use of acyl phosphonates as a coupling partner for rhodium-catalyzed [2+2+2] cycloaddition: unexpected dependence of the reactivity on structures of a,w-diynes.
[摘要]：A cationic rhodium(I)-H8-BINAP complex catalyzes a [2+2+2] cycloaddn. of 1,6- and 1,7-diynes with acyl phosphonates in high yields with high regioselectivity. Interestingly, the reactivity of a,w-diynes toward acyl phosphonates is highly dependent on their own structures.
