Diarylrhodates as Promising Active Catalysts for the Arylation of Vinyl Ethers with Grignard Reagents
Anionic diarylrhodium complexes,
generated by reacting [RhCl(cod)]<sub>2</sub> with 2 equiv of aryl
Grignard reagents, were found to be
effective active catalysts in cross-coupling reactions of vinyl ethers
with aryl Grignard reagents, giving rise to the production of vinyl
arenes. In this catalytic system, vinyl-O bonds were preferably cleaved
over Ar–O or Ar–Br bonds. A lithium rhodate complex
was isolated, and its crystal structure was determined by X-ray crystallography
