Experimental Selection Logic for Pentafluorophenyl-Based Systems: Practical Judgment from Active Esters and Pre-Activated Monomers to Downstream Transformations

When evaluating pentafluorophenol (PFP-OH)-related systems for experimental use, the first step is to identify the specific role that the “pentafluorophenyl” group plays in the current route. It may serve simply as a precursor for preparing an active ester, may already be incorporated into a ...
