WebThe thiol-ene reaction, known for over 100 years,29is, simply, the hydrothiolation of a CC bond, Scheme 1. Historically, in the polymer/materials fields the reaction has been most widely employed as a means of preparing near-perfect networks and films as exemplified by the work of Hoyle and co-workers23,30–39and Bowman et al.40–46 Thiols having the structure R−SH, in which an alkyl group (R) is attached to a sulfhydryl group (SH), are referred to as alkanethiols or alkyl thiols. Thiols and alcohols have similar connectivity. Because sulfur atoms are larger than oxygen atoms, C−S bond lengths – typically around 180 picometres – are … See more In organic chemistry, a thiol , or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The −SH functional group itself is referred to as either a thiol group … See more There are several ways to name the alkylthiols: • The suffix -thiol is added to the name of the alkane. This method is nearly identical to naming an alcohol and is used by the IUPAC, e.g. CH3SH would be methanethiol. • The … See more In industry, methanethiol is prepared by the reaction of hydrogen sulfide with methanol.

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 ...
