Dimethyl sulfate is a reagent for the methylation of phenols, amines, and thiols. One methyl group is transferred more quickly than the second. Methyl transfer is assumed to occur via an SN2 reaction. Compared to other methylating agents, dimethyl sulfate is preferred by the industry because of its low cost and high reactivity. Commonly Me2SO4 is employed to methylate phenols. Some simple alcohols are also suitably … WebAs discussed below, dimethyl sulfoxide (DMSO) is now known to be a major product (over 50%) of the reaction of the adduct with O 2. The mechanism of OH reaction with methyl mercaptan (CH 3 SH) (k OH (298 K) = 3.3×10 −11 cm 3 molecule −1 s −1) is unclear; however, it appears that the reaction leads to CH 3 S radical formation. Although a ...
