ChemInform Abstract: Sequential Palladium Catalyzed Coupling-Cyclocondensation-Coupling (C3) Four-Component Synthesis of Intensively Blue Luminescent Biarylsubstituted Pyrazoles

1‐, 3‐ and 5‐biarylsubstituted pyrazoles are efficiently obtained by microwave‐assisted consecutive four‐component synthesis including a sequential Pd‐catalyzed coupling‐condensation‐coupling, a one‐pot sequence which combines Sonogashira alkynylation and Suzuki arylation intercepted by pyrazole for...

description	1‐, 3‐ and 5‐biarylsubstituted pyrazoles are efficiently obtained by microwave‐assisted consecutive four‐component synthesis including a sequential Pd‐catalyzed coupling‐condensation‐coupling, a one‐pot sequence which combines Sonogashira alkynylation and Suzuki arylation intercepted by pyrazole forming cyclocondensation of the ynone intermediate.
