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.
preparation of NiCRA (NaH-t-AmONa-Ni(OAc)2) in the presence of 2,2′-bipyridine (bpy) leads to a new reagent (termed NiCRA-bpy) which is shown to be one of the most efficient Ni based reagents reported so far for the homocoupling of aryl and vinyl halides (including chlorides). The homo coupling of cis- and trans-β-bromostyrenes is shown to be stereospecific.
