摘要
Successive treatment of 1-trimethylsilyl-2,3-butadienes with iodine and tetra-n-butylammonium fluoride in the same flask affords 2-iodo-1,3-butadienes in good yields and their palladium-catalyzed carbonylation and alkynylation allows introduction of ester and alkynyl groups to the 2-position bearing an iodine atom leading to various 2,3-disubstituted 1,3-butadienes.
