Abstract

Abstract An efficient and straightforward copper-catalyzed method allowing vinylation of N-or O-nucleophiles with di-or trisubstituted vinyl bromides is reported. The procedure is applicable to a broad range of substrates since N-vinylation of mono-, di-, and triazoles as well as O-vinylation of phenol derivatives can be performed with catalytic amounts of copper iodide and inexpensive nitrogen ligands 3 or 8. In the case of more hindered vinyl ...
