Ethyl lactate mediated thioacetalization of aldehydes at ambient temperature
Wan, Jie-Ping,Jing, Yanfeng,Liu, Yunyun
, 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.
Cerium triflate: An efficient and recyclable catalyst for chemoselective thioacetalization of carbonyl compounds under solvent-free conditions
Kumar, Anil,Rao, M. Sudershan,Kameshwara Rao
experimental part, p. 135 - 140 (2010/05/18)
A simple and efficient chemoselective thioacetalization of carbonyl compounds has been achieved using Ce(OTf)3 (10 mol-%) as a catalyst under solvent-free conditions. Advantages of the methodology include very short reaction times, excellent yi
Green, catalyst-free thioacetalization of carbonyl compounds using glycerol as recyclable solvent
Perin, Gelson,Mello, Luzia G.,Radatz, Cátia S.,Savegnago, Lucielli,Alves, Diego,Jacob, Raquel G.,Lenard?o, Eder J.
experimental part, p. 4354 - 4356 (2010/09/12)
We describe herein the use of glycerol as an efficient and a recyclable solvent in the thioacetalization of aldehydes and ketones. The catalyst-free reactions proceed easily using glycerol at 90 °C and the corresponding thioacetals were obtained in good to excellent yields. Glycerol was recovered and utilized for further thioacetalization reactions.
An indium-TMSCl promoted reaction of diphenyl diselenide and diorganyl disulfides with aldehydes: novel routes to selenoacetals, thioacetals and alkyl phenyl selenides
Ranu, Brindaban C.,Saha, Amit,Mandal, Tanmay
experimental part, p. 2072 - 2078 (2009/07/11)
The reactions of diphenyl diselenide and dialkyl disulfides with aldehydes in the presence of In-TMSCl have been investigated. Aliphatic aldehydes provide the corresponding selenoacetals and aromatic aldehydes lead predominantly to benzyl phenyl selenides
Selenonium ionic liquid as an efficient catalyst for the synthesis of thioacetals under solvent-free conditions
Lenard?o, Eder J.,Borges, Elton L.,Mendes, Samuel R.,Perin, Gelson,Jacob, Raquel G.
, p. 1919 - 1921 (2008/09/19)
Acidic ionic liquid butyl ethyl phenyl selenonium tetrafluoroborate, [BEPSe]BF4, was successfully employed as a catalyst for the synthesis of several dithioacetals in the absence of a solvent. The method is general and selectively afforded thioacetals derived from aldehydes and ketones in good yields.
Synthesis of Aldehydes from Phenylthiotrimethylsilylmethane
Ager, David J.
, p. 1131 - 1136 (2007/10/02)
Phenylthiotrimethylsilylmethyl-lithium (4) reacts with alkyl halides to give 1-phenylthio-1-trimethylsilylalkanes (5), which can also be prepared by the addition of alkyl-lithium to 1-phenylthio-1-trimethylsilylethene (8), or from bis(phenylthio)acetals (11).The 1-phenylthio-1-trimethylsilylalkanes (5) can be converted into the corresponding aldehyde (15) by oxidation to the sulphoxide (13), thermal rearrangement, and hydrolysis of the resultant O-silyl thioacetal (14).
