Syntheses and reactions of (R)-(C10H6)2M2 (M=SnMeCl2, SnMe2Cl, SnMe(OTf)2, SnMe2OTf, SiMe2I) as novel chiral 2,2′-bis-metallic-1,1′-binaphthyl catalysts
(R)-(C10H6)(2)M-2 (M=SnMeCl2, SnMe2Cl, SnMe(OTf)(2), SnMe2OTf, SiMe2I) were synthesized as novel chiral 2,2'-bismetallic-1,1'-binaphthyl catalysts. The catalytic activities were evaluated in the Diels-Alder reaction of methacrolein and cyclopentadiene and the asymmetric acylation reaction of racemic 1-phenyl-1,2-ethanediol.
