Copper/N,N,N',N'-tetramethylethylenediamine (Cu/TMEDA)-catalyzed ambient temperature tandem reactions of isothiocyanates with 2-iodophenols or 2-iodoanilines in water without the protection of an inert atmosphere are described, which provide a simple, rapid, environmental method for the synthesis of a variety of 2-iminobenzo-1, 3- oxathioles and 2-aminobenzothiazoles in good yields. More important, the present reaction process needs only low amounts of copper catalyst (1mol%) and can yield the products on a gram scale.

supporting information, p. 2283 - 2287 (2012/11/07)
The 1,10-phenanthroline-catalyzed tandem reaction of 2-iodoaniline with isothiocyanate in water is described, which provides an environmentally benign, efficient and simple route for the preparation of 2-aminobenzothiazoles. The present tandem process shows broad substrate scope in the absence of transition metals and phase-transfer catalysts. Copyright
