Abstract
A general and efficient copper(II) bromide catalyzed substitution reaction of propargylic alcohols with carbon and heteroatom-centered nucleophiles, such as alcohols and thiols, leading to the construction of C-O and C-S bonds has been developed. High product yields were obtained with excellent regioselectivity.
Key words
propargylic ethers - alcohols - thiols - etherification - nucleophilic substitution
