WebAug 11, 2014 · Thiols are also more nucleophilic than alcohols, especially in basic solution. Thioethers are in general formed by reaction of the thiol, in a basic solution, with a halide. Much of the chemistry used for the protection of a thiol can also be used for the protection of the selenol group, which is not nearly as common in organic synthesis, but ... http://employees.oneonta.edu/odagomo/Chapter_7%20Alcohols,%20Phenols%20and%20Thiols.ppt WebFeb 20, 2024 · Open in figure viewer PowerPoint. ...
