Ionic liquids are solvents general enough to conduct a multi-step process in organic synthesis. We show that both the preparation of starting materials (thioacetals and enoxysilane) as well as their coupling can be realized in such medium.
Ethyl lactate mediated thioacetalization of aldehydes at ambient temperature

, p. 1302 - 1305 (2016/09/28)
Dithioacetalization reactions of aldehydes with thiols/thiophenols have been successfully achieved at room temperature by employing the green, bio-based ethyl lactate as the reaction medium. By means of this sustainable approach, a class of dithioacetals has been acquired with high diversity and efficiency.
Silica-supported phosphorus pentoxide: A reusable catalyst for S,S-acetalization of carbonyl groups under ambient conditions

experimental part, p. 85 - 91 (2012/01/06)
Phosphorus pentoxide supported on silica gel (P2O 5/SiO2) efficiently acts as a highly active and reusable catalyst for cyclic and non-cyclic S,S-acetalization of a variety of carbonyl compounds under mild, solvent-free an
Catalytic syntheses of γ-functionalized α-keto esters from thioacetals and N,O-acetals
Krebs, Anke,Bolm, Carsten
experimental part, p. 4055 - 4060 (2011/06/24)
Ethyl 2-(trimethylsilyloxy)acrylic ester (1a) reacts with thioacetals providing the corresponding α-keto-γ-thio esters in good to satisfactory yields. Whereas aminals do not react, N,O-acetals lead to γ-amino-α-keto esters in good to excellent yields. All reactions proceed under mild reaction conditions, and no additional work up is required. Subsequent transformations of the obtained products to the corresponding α-oximes have been demonstrated.
Indium(III) chloride catalyzed efficient conversion of carbonyl compounds to 1,3-dithioacetals
Yadav,Subba Reddy,Pandey, Sushil Kumar
, p. 715 - 719 (2007/10/03)
Several aldehydes and ketones were efficiently converted into their corresponding dithioacetals and 1,3-dithianes in high yields using catalytic amount of indium(III) chloride in dichloromethane.
Tellurium tetrachloride as a mild and efficient catalyst for dithioacetalization
Tani, Hiroyuki,Masumoto, Kazunori,Inamasu, Tokuo,Suzuki, Hitomi
, p. 2039 - 2042 (2007/10/02)
A variety of aldehydes and aliphatic ketones were converted into the corresponding dithioacetals at room temperature in good yields by using small amounts of tellurium tetrachloride as a mild Lewis acid catalyst.
