ANHYDROUS LANTHANUM TRICHLORIDE, A MILD AND CONVENIENT REAGENT FOR THIOACETALIZATION
Garlaschelli, Luigi,Vidari, Giovanni
, p. 5815 - 5816 (1990)
Carbonyl compounds are thioacetalyzed easily by 1,2-ethanedithol in the presence of anhydrous LaCl3.
Chemoselective thioacetalisation of aldehydes catalysed by Fe3+-montmorillonite
Choudary, Boyapati M.,Sudha, Yepuri
, p. 2993 - 2997 (1996)
Aldehydes were cleanly and selectively converted to the corresponding dithioacetals almost quantitatively with catalytic amounts of Fe3+-exchanged montmorillonite (Fe3+-mont) even in the presence of ketones. Copyright

Tamami,Borujeny, K. Parvanak
, p. 4253 - 4258 (2003)
Silica gel supported aluminium chloride is shown to be a mild chemoselective catalyst for dithioacetalization of carbonyl compounds.
Visible-light promoted dithioacetalization of aldehydes with thiols under aerobic and photocatalyst-free conditions

supporting information, p. 5117 - 5122 (2018/11/24)
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.
Indium-Catalyzed Reductive Dithioacetalization of Carboxylic Acids with Dithiols: Scope, Limitations, and Application to Oxidative Desulfurization
Nishino, Kota,Minato, Kohei,Miyazaki, Takahiro,Ogiwara, Yohei,Sakai, Norio
, p. 3659 - 3665 (2017/04/11)
In this study an InI3-TMDS (1,1,3,3-tetramethyldisiloxane) reducing system effectively catalyzed the reductive dithioacetalization of a variety of aromatic and aliphatic carboxylic acids with 1,2-ethanedithiol or 1,3-propanedithiol leading to the one-pot preparation of either 1,3-dithiolane derivatives or a 1,3-dithiane derivative. Also, the intact indium catalyst continuously catalyzed the subsequent oxidative desulfurization of an in situ formed 1,3-dithiolane derivative, which led to the preparation of the corresponding aldehydes.
