DOI: 10.1002/app.44921
Abstract: Fluorinated acrylate emulsions have been extensively applied for hydrophobic surface coatings. To obtain fluorinated emulsions of low surface energy, amphiphilic sulfonyl macro emulsifiers consisting of 2-(perfluorohexyl) ethyl acrylate (PFHEA) and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS) were designed… read more here.

DOI: 10.1021/acs.orglett.0c02921
Abstract: A nickel-catalyzed enantioselective transfer hydrogenation and deuteration of N-sulfonyl imines was developed. Excellent α-selectivity and high deuterium content were achieved by using inexpensive 2-propanol-d8 as a deuterium source. As a highlight, no deuteration of β-C-H… read more here.
