The Stereochemistry of Cross-coupling Adducts of Norbornenes with Butadiene Catalyzed by Ni Complex
The stereochemistry of cross-coupling adducts of norbornenes with butadiene catalyzed by Ni complex generated in situ by NiBr2(Ph3P)2 and NaBH4 in ethanol was investigated.The configuration of four-member cross-coupling products could be confirmed by means of independent synthesis.
