Described herein is a simple, novel, one-pot acylamination reaction of unactivated alcohols. This reaction employs the combination of PCl3 and triflic anhydride (Tf2O) or copper triflate Cu(OTf)2, which serves as a source of P(IV)-activated complex for nitriles to react under the Ritter-type mechanism. The synthetic utility of Tf2O-promoted reactions was demonstrated by its effectiveness to generate different
An object of the present invention is to provide a material for blood purification having the capability to remove cytokines and activated leukocyte-activated platelet complexes. The present invention provides a material for blood purification, the material containing a water-insoluble material in which a ligand having an amide group(s) and an amino group(s) is bound to a substrate, wherein the content of the amide group(s) is 3.0 to 7.0 mmol per 1 g dry weight of the water-insoluble material; and wherein the content of the amino group(s) is 1.0 to 7.0 mmol per 1 g dry weight of the water-insoluble material.
