Non-toxic ligands in samarium diiodide-mediated cyclizations
Samarium diiodide-mediated cyclizations of aryl radicals carried out in the presence of several nitrogen ligands (triethylamine, 1,8-diazabyciclo[5.4.0]undec-7-ene and 1,1-3,3-Tetramethylguanidine) are described. The yields and the selectivities observed are comparable to the ones obtained by using hexamethylphosphoramide.
