Triflate, trimethylsilyl vinyl substitutions

Commercially available trimethylvinylsilanes can be vinylated using either vinyl triflates or vinyl iodides in the presence of silver salts, in a reaction catalyzed hy palladium acetate in the presence of triethylamine. The resulting 3-substituted 1-trimethylsilyl-1,3-dienes are obtained in reasonable to good yields. ... [Pg.461]

An optically pure chiral alkene-Fp complex is formed by reaction of the (Z)-2-butene-Fp complex with (/ ,R)-2,3-butanediol. Nucleophiles are added to this complex in a complete stereoselective way. Ring opening of the cyclic alkyl-Fp complexes with trimethylsilyl triflate leads to substituted vinyl ether-Fp complexes as pure enantiomers. The configurational stability of those complexes is limited, however, which requires immediate demetalation to the organic products (Scheme 4-75). ... [Pg.600]
