A novel synthesis of 1,1′-unsymmetrical disubstituted heteroarylferrocene
摘要:
Stepwise Stille coupling reaction of 1,1'-bis(tributylstannyl)ferrocene with different heterocyclic bromides was achieved in the presence of Pd-complex catalyst via two steps to afford unsymmetrical 1,1'-disubstituted heteroarylferrocene compounds. (C) 2000 Elsevier Science B.V. All rights reserved.
