A Method for Obtaining Defined End Groups of Polymethacrylates Prepared by the RAFT Process during Aminolysis was written by Roth, Peter J.;Kessler, Daniel;Zentel, Rudolf;Theato, Patrick. And the article was included in Macromolecules (Washington, DC, United States) in 2008.Quality Control of Benzyl benzodithioate This article mentions the following:
We presented a simple modification of the aminolysis of polymethacrylates prepared by the RAFT process overcoming the problems of thiolactone and side product formation. The method uses the high reactivity of Me methanethiosulfonate toward thiols, thus favoring Me disulfide formation even in the presence of oxygen. The transformed disulfide end group showed a higher affinity toward a gold surface than the dithioester end group and could successfully be employed for encapsulation of gold nanoparticles. This method enables polymethacrylates to be grafted onto metal surfaces and also opens new routes to end-group functionalization of RAFT polymers. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7Quality Control of Benzyl benzodithioate).
Benzyl benzodithioate (cas: 27249-90-7) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Quality Control of Benzyl benzodithioate
