A novel photocatalyst-free visible-light-mediated dithioacetalization of aldehydes and thiols has been developed. This protocol is operationally simple, mild and atom-economical, which provides an environmental benign access to dithioacetals at room temperature under aerobic conditions.
Aluminum hydrogen sulfate [Al(HSO4)3] as an efficient catalyst for the preparation of thioacetals
Ghashang, Majid
, p. 2837 - 2842 (2013/07/26)
Aluminum hydrogen sulfate, as a heterogeneous solid acid catalyst, has been used for the mild conversion of carbonyl compounds to their thioacetals using 1,2- and 1,3-dithiol under ambient conditions with short reaction times in high to excellent yield in

Pourmousavi, Seied Ali,Hadavankhani, Majid,Zinati, Zahra
experimental part, p. S495-S501 (2012/05/31)
A rapid and efficient method for the transthioacetalization of acylals (1,1-diacetates) and acyclic and cyclic acetals is described. The reaction was carried out using 1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane tribromide (1 mol%). The yield of the transthioacetalization was high and reaction conditions involve the use of acetonitrile as the solvent at room temperature; isolation is simple and the products are nearly pure.
Chemoselective dithioacetalization of carbonyl compounds using magnesium hydrogensulfate as efficient heterogeneous catalyst

Jin,Sun,Ma,Li
, p. 1669 - 1673 (2007/10/03)
Aldehydes and ketones were thioactalized with 1,2-ethanedithiol in the presence POCl3-montmorillonite at room temperature in excellent yields.
Comparative radioprotective activity of various pentagonal compounds with two heteroatomes
Robbe,Fernandez,Dubief,et al.
, p. 235 - 243 (2007/10/02)
Various heterocyclic compounds with two heteroatomes were synthesized and their potential radioprotective activity was tested. This study shows the interest of phenylthiazolidines derivatives in chemical radioprotection.
