A mild and efficient transthioacetalization of aldehyde acetals and oxathioacetals was carried out using 2,4,6-trichloro-1,3,5-triazine as a mild and inexpensive catalyst. Chemoselective transacetalization is impressive as aldehyde O,O- and O,S-acetals ar
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.
Unprecedented polymer-supported π-acid: Synthesis and its application as a promoter to the monothioacetalization of acetals
Masaki, Yukio,Tanaka, Nobuyuki,Miura, Tsuyoshi
, p. 5799 - 5802 (2007/10/03)
A novel polymer was synthesized by copolymerization of styrene monomer bearing dicyanoketene acetal functionality and ethylene glycol dimethacrylate, and used successfully as a recyclable π-acid catalyst in monothioacetalization of aromatic, aliphatic, acyclic, and cyclic acetals with thiophenol and phenylthiotrimethylsilane.
Catalyst-dependent selective synthesis of O/S- and S/S-acetals from enol ethers
Braga,Silveira,Dornelles,Zeni,Galarza,Wessjohann
, p. 3155 - 3162 (2007/10/02)
Enol ethers are reacted with mercaptanes to give the corresponding O/S- or S/S-acetals in medium to high yield. Either product can be formed selectively depending on the acid catalyst and the reaction time applied.
A Convenient Method for the Transformation of Alkenyl Sulfides to 2-(Phenylthio)alkanenitriles, Homoallyl Sulfides, and Thioacetals
Takeda, Takeshi,Kaneko, Yuichiro,Nakagawa, Hitoshi,Fujiwara, Tooru
, p. 1963 - 1966 (2007/10/02)
2-(Phenylthio)alkanenitriles, homoallyl sulfides, and thioacetals were obtained in good yields by the reaction of alkenyl sulfides with the corresponding silyl nucleophiles via thionium ion intermediates.
