Phosphobetaine
WebApr 1, 2024 · A series of difluorinated phosphonium salts were obtained by reaction of difluoromethylene phosphobetaine with halogenating reagents, as well as arylsulfenyl and arylselenyl chlorides. The reaction proceeds via decarboxylation of the phosphobetaine followed by trapping of the difluorinated phosphorus ylide by heteroatom-centered … Webbetaine hydrogels, consisting of phosphobetaine, sulfobetaine, or carboxybetaine polymers, are also of interest as a new type of hydrogels.25,26 They can be prepared through initiating a mixed solution containing a zwitterionic betaine monomer and a cross-linker. Due to their excellent biocompatibility, anti-biofouling
