Muthusamy, Sengodagounder,Arulananda Babu, Srinivasarao,Gunanathan, Chidambaram
, p. 7897 - 7901 (2002)
Protection of a variety of carbonyl compounds as thioacetals using indium triflate, a mild Lewis acid catalyst, was achieved at ambient temperature in very good yield. Transthioacetalization of oxyacetals into thioacetals was also achieved in an excellent
Transdithioacetalization of acetals, ketals, oximes, enamines and tosylhydrazones catalysed by natural kaolinitic clay
Jnaneshwara,Barhate,Sudalai,Deshpande,Wakharkar,Gajare,Shingare,Sukumar
, p. 965 - 968 (1998)
Natural kaolinitic clay efficiently catalyses the transdithioacetalization of acetals, ketals, oximes, enamines and tosylhydrazones with ethane-1,2-dithiol and propane-1,3-dithiol to produce the corresponding dithiolanes in high yields.
A rapid and efficient method of thioacetalization of carbonyl compounds catalysed by POCl3-montmorillnite
Jin,Sun,Ma,Li
, p. 1669 - 1673 (2001)
Aldehydes and ketones were thioactalized with 1,2-ethanedithiol in the presence POCl3-montmorillonite at room temperature in excellent yields.
Highly efficient dithioacetalization of carbonyl compounds catalyzed with iodine supported on neutral alumina
Deka, Nabajyoti,Sarma, Jadab C.
, p. 794 - 795 (2001)
Aldehydes and ketones are protected as their corresponding dithioacetals with ethane-1,2-dithiol in the presence of a catalytic amount of iodine supported on neutral alumina surface. This is a high yielding method of carbonyl group protection under mild,
Promotion of 1,3-Dithiolanes using a Bentonitic Clay as Catalyst
Aceves,Arroyo,Vargas,Miranda,Cabrera,Delgado
, p. 71 - 76 (2004)
The reactions between 1,2-ethandithiol with several carbonylic compounds to form the corresponding 1,3-dithiolanes were performed using a natural clay as promotor. The target molecules are used as reagents to obtain fine chemicals, herbicides, fungicides,
Thioacetalization of aldehydes and ketones in SDS micelles
Bahrami, Kiumars,Khodaei, Mohammad Mehdi,Tajik, Maryam,Soheilizad, Mehdi
, p. 397 - 403 (2011)
Aromatic aldehydes have been successfully converted into their corresponding dithioacetal, dithiolane and dithiane derivatives in excellent yields with thiol (benzyl thiol and thiophenol), 1,2-ethanedithiol and 1,3-propanedithiol using trichloroacetic acid in sodium dodecyl sulfate micelles. The same procedure is applicable to ketones, but they need more time to be converted into their thioacetals. Image Presented.
An expedient carbon–sulfur bond formation explored through the cellulose sulfonic acid (CSA) catalyzed dithioacetal protection of carbonyl compounds
