1,9-Decadiyne, 97%, Thermo Scientific Chemicals
Description
One-step synthesis of carbametacyclophane 3 from 1,9-decadiyne and diethyl acetylenedicarboxylate is described. The use of 1,9-decadiyne as a nucleophile led only to the monoalkynylation product, a selectivity that would be difficult to achieve with a catalytic in situ metalation process. 1,9-decadiyne reacts with iodobenzene (excess) to afford the bis-Sonogashira coupling product in excellent yield. 1,9-Decadiyne was dihydrated and gave 2,9-decanedione in 92% yield.
