Scavenging of Fluorinated N,N‘-Dialkylureas by Hydrogen Binding: A Novel Separation Method for Fluorous Synthesis
摘要:
[GRAPHICS]A dramatic solubility increase in fluorous solvents is observed for N,N ' -di(polyfluoroalkyl)ureas when hydrogen binding complexes are formed with commercially available perfluoroalkanoic acid scavengers. As a case example, analytically pure peptides and esters are obtained using this novel separation method.
