experimental part, p. 2616 - 2626 (2010/02/16)
A new rearrangement of 1-(diarylmethyl)-2-isothiocyanatobenzenes into 2,4-diaryl-4H-3,1-benzothiazine derivatives is described. Treatment of the starting compounds with aluminum trichloride under Friedel-Crafts conditions leads to migration of an aryl sub
Aromatic ring transfer-a new synthesis of 2,4-diaryl-4H-3,1-benzothiazines

A new synthetic approach to 2,4-diaryl-4H-3,1-benzothiazines is described based on the rearrangement of 2-isothiocyano triarylmethanes in the presence of AlCl3. An aryl ring is found to migrate to the carbon atom of an isothiocyano group follow
