Sulfonic acid functionalized nano γ-Al2O3 is easily prepared by the reaction of nano γ-Al2O3 with 1,3-propane sulfone. This reagent can be used as an eficient catalyst for the synthesis of thioamides. This new method consistently has the advantages of excellent yields and short reaction times. Further, the catalyst can be recovered for several times.

Three-component reactions involving amines, aldehydes, and elemental sulfur powder are reported to afford thioamides in a simple one-pot procedure in the absence of a catalyst. A variety of thioamides can be obtained in good to excellent yields up to 88 %. Three-component reactions involving amines, aldehydes, and sulfur powder afford thioamides in a simple one-pot procedure. A variety of substituted thioamides are obtained in good to excellent yields up to 88 %. Copyright
Efficient synthesis of thiobenzanilides by Willgerodt-Kindler reaction with base catalysts
Okamoto, Ken,Yamamoto, Takakazu,Kanbara, Takaki
, p. 2687 - 2690 (2008/02/11)
Willgerodt-Kindler reaction between anilines and benzaldehydes readily proceeded in the presence of catalytic amount of Na2S·9H 2O to give thiobenzanilides in moderate to good yields. The base catalyst was also available for preparation of primary thiobenzamide. Georg Thieme Verlag Stuttgart.
