[4 + 2] Cycloadditions of Halogeno Thiazyls with 2‐Chloropentafluoro‐1,3‐butadiene Reactions of (XSN) n ( n =3, 1; X=Cl, F) with 2‐chloropentafluoro‐1,3‐butadiene provide the 1λ 4 ,2‐thiazines 1a and 1b . Fluorination with KF converts 1a in 88% yield to 1b . CH 3 OH reacts with 1b to form the 1‐methoxy derivative 1c . The structure of 1c was determined by single‐crystal X‐ray diffraction analysis. With water 1a forms the 1,2‐thiazin‐3‐one 1‐oxide 2.
