The combination of TiCl3OTf with 1-butyl-3-methylimidazolium bromide is found to be an efficient and novel catalytic system for chemoselective one-pot transformation of arylaldoximes to their corresponding thioamides in high to excellent yields.

Crown etherscontaining a thiazole subcyclic unit are prepared from the reactions of 1,3-bis[2(4-hydroxymethylthiazoyl)]benzene with di-p-tosylates of corresponding di, tri, tetra, pentaethylene glycols in the presence of potassium hydride. However, if the cavity size in the ring system is small, [2+2] cyclization adduct also is formed.

An aryne precursor with a potential to perform domino aryne chemistry was proposed and synthesized. The reaction of this reagent with benzothioamide derivatives could afford 2,4-disubstituted benzothiazole with sequential incorporation of C-S, C-N, and C-C bonds on the consecutive three positions of the aryne precursor.
