Cyclomagnesation of cycloalkynes with the use of RMgR’ catalyzed by zirconium complexes
摘要:
The intermolecular cyclomagnesation of cycloalkynes and joint cyclomagnesation of cycloalkynes and disubstituted acetylenes was carried out by treating with RMgR' (R, R' = Et, Bu, H1g) in the presence of Cp2ZrCl2 as a catalyst. As a result new unsaturated bi-and tricyclic organomagnesium compounds were obtained in high yields.
