Microwave-assisted cross-coupling of 3-chloro-2-pyrazolines and 3-chloro-1-phenyl-1,4,5,6-tetrahydropyridazine with aryl boronic acids

3-Chloro-l-phenyl-2-pyrazoliiie and 3-chloo-1-phenyl-1,4,5,6-tetrahydropyridazine were coupled with aryl boronic acids in good yields under microwave heating conditions (140 degrees C, 5 min). (c) 2005 Elsevier Ltd. All rights reserved.
