Downey, C. Wade,Johnson, Miles W.,Tracy, Kathryn J.
, p. 3299 - 3302 (2008/09/19)
(Chemical Equation Presented) Various ketones, esters, amides, and thioesters add in high yield to dimethyl acetals in the presence of silyl trifluoromethanesulfonates and an amine base. Acetals derived from aryl, unsaturated, and aliphatic aldehydes are

(matrix presented) Mukaiyama-type aldol coupling of typical silyl enolates 2-4 with aryl or vinyl aldehydes and acetals was realized in the presence of 1-5 mol % of MgI2 etherate (1) in a mild, efficient, and highly chemoselective manner. Iodid
Polymer-supported dicyanoketene acetal as a π-acid catalyst: Monothioacetalization and carbon-carbon bond formation of acetals
Tanaka, Nobuyuki,Miura, Tsuyoshi,Masaki, Yukio
, p. 1010 - 1016 (2007/10/03)
Polymeric dicyanoketene acetals (DCKA) were synthesized by copolymerization of styrene and divinylbenzene or ethylene glycol dimethacrylate. These novel polymers could be used successfully as recyclable π-acid catalysts in monothioaCetalization or carbon-carbon bond forming reaction of acetals.
Carbon-carbon bond formation and reduction of aldehydes, ketones and acetals with silylated nucleophiles catalysed by tetracyanoethylene
Miura, Tsuyoshi,Masaki, Yukio
, p. 2155 - 2158 (2007/10/02)
Tetracyanoethylene catalyses the reactions of aldehydes, ketones and acetals with silylated nucleophiles such as trimethylsilyl cyanide, allyltrimethylsilane, aryl methyl ketone trimethylsilylenol ethers and triethylsilane to promote carbon-carbon bond formation and reduction under neutral conditions.All the evidence strongly suggested that the reactions occur through single electron transfer (SET) mechanism based on UV spectroscopic measurements.

Miura, Tsuyoshi,Masaki, Yukio
, p. 1659 - 1660 (2007/10/02)
Tetracyanoethylene catalyses the reactions of aldehydes, ketones and acetals with silylated carbon and hydrogen-nucleophiles to promote carbon-carbon bond formation and reduction under neutral conditions.

Hayashi, Yujiro,Mukaiyama, Teruaki
, p. 1811 - 1814 (2007/10/02)
Allyl ethers are oxidized by DDQ to generate the corresponding cationic species, which in turn react with silyl carbon nucleophiles in the presence of a catalytic amount of lithium perchlorate to afford the coupled products in a one-pot procedure in good
