Synthetic Methods, III [1]: Sulfated Zirconia Catalyzed Thioacetalization of Carbonyl Compounds
Bandgar,Kasture
, p. 1305 - 1308 (1996)
Sulfated zirconia effectively catalyzes the reaction of carbonyl compounds with 1,2-ethanedithiol or thiophenol to afford the corresponding dithioacetals as useful organosulfur synthons. Isolation of pure products in high yields by simple filtration and e

Patney
, p. 2259 - 2260 (1991)
Carbonyl compounds are rapidly thioacetalized in near quantitative yields by using anhydrous iron(III) chloride dispersed on silica gel at room temperature.
Envirocat EPZG(R) as an efficient heterogenous catalyst for thioacetalization of carbonyl compounds
Kasture,Bandgar,Sarkar,Wadgaonkar
, p. 1579 - 1583 (1996)
The reaction of carbonyl compounds with 1,2-ethanedithiol was efficiently catalyzed by Envirocat EPZG(R) to afford the corresponding dithioacetals in excellent yields.

Chemoselective dithioacetalization and oxathioacetalization of carbonyl compounds using alumina sulfuric acid as catalyst
Shaterian, Hamid Reza,Hosseinian, Asghar,Ghashang, Majid
experimental part, p. 4097 - 4106 (2009/04/11)
Carbonyl compounds have been successfully converted into their corresponding dithiolane, dithiane, and oxathiolane derivatives using a catalytic amount of alumina sulfuric acid (Al2O3-SO3H) with excellent yields at room temperature in short reaction times under mild conditions. This simple method is a highly chemoselective procedure for protection of aldehydes in the presence of ketones, and the heterogeneous catalyst can be recovered and reused several times without any loss of its activity.

An efficient method for thioacetalization of carbonyl compounds in the presence of a catalytic amount of benzyltriphenylphosphonium tribromide under solvent-free conditions
Hajipour, Abdol R.,Pourmousavi, Seied A.,Ruoho, Arnold E.
, p. 921 - 937 (2008/02/05)
A variety of carbonyl compounds have been successfully converted to the corresponding thioacetal derivatives in good to excellent yields on the reaction of carbonyl compounds with 1,2-ethanedithiole, 1,3-propanedithiol, and ethanethiol in the presence of
