Highly selective anti-Markovnikov addition of thiols to vinyl ethers under solvent- and catalyst-free conditions
A simple and efficient protocol for the anti-Markovnikov addition of thiols to vinyl ethers under solvent- and catalyst-free conditions has been established. A series of thiol ethers containing oxygen atom were obtained with good to excellent yields.
SYNTHESIS OF VINYLCYCLOPENTANES FROM VINYLCYCLOPROPANES AND ALKENES PROMOTED BY BENZENETHIYL RADICAL
The reaction of dimethyl 2-vinylcyclopropane-1,1-dicarboxylate with butyl vinyl ether in the presence of a catalytic amount of PhSH provides dimethyl 3-butoxy-4-vinylcyclopentane-1,1-dicarboxylate in 82percent yield.
