reaction. Both were active in the two-component click cycloaddition reaction of terminalalkynes and organic azides and three-component cycloaddition reaction that employs various terminalalkynes, NaN3 and organic halides with the advantage of excellent yields, low catalyst dosage, short reaction time. The MWNTs@NHC-Cu catalyst could be separated from the reaction system at the end of the reaction and

A novel, micelle-based fluorescence system capable of selective and sensitive signal transduction for non-transferrin-bound iron (NTBI) in serum was devised.
nickel-catalyzed cyanation of phenol derivatives with metal-free cyanating agents, aminoacetonitriles, is described. A nickel-based catalytic system consisting of a unique diphosphine ligand such as dcype or dcypt enables the cyanation of versatile phenol derivatives such as aryl carbamates and aryl pivalates. The use of aminoacetonitriles as a cyanating agent leads to an environmentally and easy-to-use method
