Thiol mechanism

WebThiols and sulfides are the "sulfur equivalent" of alcohols and ethers. You can replace the oxygen atom of an alcohol with a sulfur atom to make a thiol; similarly, you can replace the oxygen atom in an ether with S to make the corresponding alkyl sulfide. This is because thiols contain the C-S-H functional group, while sulfides contain the C-S ... WebThiol-ene photopolymerizations proceed via a free-radical step-growth mechanism that allows shrinkage stress dissipation during network cross-linking. Unlike free-radical chain …
