, p. 619 - 624 (2022/01/20)
A Ni-catalyzed cross-coupling of readily accessible O-alkyl xanthate esters or thiocarbonyl imidazolides and organozinc reagents for the synthesis of thiocarboxylic acid derivatives has been developed. This method benefits from a fast reaction time, mild reaction conditions, and ease of starting material synthesis. The use of transition-metal catalysis to access a diverse range of thiocarbonyl-containing compounds provides a useful complementary approach when compared with previously established methodologies.

A metal-free C[dbnd]C bond cleavage reaction of β-nitrostyrenes in the presence of elemental sulfur and secondary amines/amides is described. Elemental sulfur serves as both a raw material and an oxidant for C[dbnd]C bond cleavage, and secondary amines or amides are both feasible nitrogen sources. Besides mild reaction condition and simple work-up procedure, the method provided thioamides with good to excellent yields.

A novel transition-metal-free cleavage reaction of C-C triple bonds in aromatic alkynes with S8 and amides furnishes aryl thioamides in moderate to excellent yields. The remarkable features of this thioamidation include the metal-free cleavage of C-C triple bond, mild reaction conditions, as well as wide substrate scope that is particularly compatible with some internal aromatic alkynes and acetamides.

A rapid, green, and efficient one-pot, three-component Kindler reaction was developed using a sulfated polyborate catalyst. The method described the reaction of aldehydes, amines/ammonium acetate, and sulfur for the synthesis of thioamides using sulfated polyborate under a solvent free condition at 100?°C. The key features of the present protocol are high yields, short reaction time, easy workup, and recyclability of a catalyst which gives economical as well as ecological rewards. The present method also has an ability to tolerate a variety of functional groups. Graphical abstract: [Figure not available: see fulltext.].
Thiol as a synthon for preparing thiocarbonyl: Aerobic oxidation of thiols for the synthesis of thioamides
Wang, Xi,Ji, Miran,Lim, Seungyeon,Jang, Hye-Young
, p. 7256 - 7260 (2014/08/18)
It is a constant challenge to develop an environmentally friendly, atom-economical, and step-economical method for the preparation of thioamides. Herein, we describe an oxidation method that affords the direct conversion of thiols to thioamides without the use of exogenous sulfur reagents. This is the first instance of a successful utilization of thiols as a synthon for the preparation of thioamides under economical conditions.
