A new and efficient synthesis of 2-arylbenzoxazoles and benzothiazoles using a copper N-heterocyclic carbene complex is described. In a simple protocol a variety of 2-substituted benzoxazoles and benzothiazoles were obtained via intramolecular coupling cyclization of 2-haloanilides/2-halothioanilides in good to excellent yields.

One-pot three-component reactions of aldehydes, amines, and sulfur are carried out in the presence of nano n-propylsulfonated magnetic γ-Fe2O3 as a catalyst for the synthesis of biologically interesting thioamide derivatives. The value of this catalytic method lies in its mild reaction catalyst and conditions, good yields, and ease of handling.
Sulfated tungstate: An efficient catalyst for synthesis of thioamides via Kindler reaction
Pathare, Sagar P.,Chaudhari, Pramod S.,Akamanchi, Krishnacharya G.
experimental part, p. 125 - 129 (2012/07/03)
New application of sulfated tungstate, a mildly acidic solid inorganic acid, as reusable heterogeneous catalyst for efficient Kindler reaction, a three component reactions of aldehydes, amines and sulfur, for synthesis of thioamides is discussed.
