Abstract:  By the effect of phosphorus tribromide on 5-(X-phenyl)-2-furfuryl alcohols 5-(X-phenyl)-2-furfuryl bromides were prepared. From these substances 5-(X-phenyl)-2-furfuryl thiocyanates were obtained by using ammonium thiocyanate. (X = 4-N0₂ , 3-NO₂, 2-N0₂,4-Cl, 3-Cl, 2-Cl, 4-Вг, H, and 4-CH₃.) Moreover, there is presented a synthesis of some isothiocyanates of 5-(X-phenyl)-2-furfuryl type based on the direct action of thiophosgene on the corresponding amines or on the heating of corresponding 5-(X-phenyl)-2-furfuryl bromides with potassium thiocyanate in dimethylformamide.
