Nickel(0)‐katalysierte Kupplung von (Tricyclo[4.1.0.0^2,7]hept‐1‐yl)‐magnesiumbromid und verwandten Grignard‐Verbindungen mit Aryl‐, Vinyl‐ und Alkinylhalogeniden

Abstract

Nickel(0)‐Catalyzed Cross Coupling Reactions of (Tricyclo[4.1.0.0 2,7 ]hept‐1‐yl)magnesium Bromide and Related Grignard Reagents with Aryl, Vinyl, and Alkynyl Halides (Tricyclo[4.1.0.0 2,7 ]hept‐1‐yl)magnesium bromide ( 1c ) and similar Grignard reagents like 2c , 3a – d , and 4 were cross‐coupled with a series of aryl, vinyl, and alkynyl chlorides or bromides in the presence of approximately 1% of [1,2‐bis(diphenyl‐phosphino)ethane]nickel dichloride (NidppeCl 2 ) leading to bridgehead‐substituted aryl‐, vinyl‐, and alkynylbicyclo[1.1.0]‐butanes in varying yields.
