Abstract The complete isomerization of the molecular ion of r ‐2‐deuterio‐2, cis ‐4, cis ‐6‐trimethyl‐1,3,5‐trithian into equal proportions of 3, 5‐ and 6‐ d 1 ‐3,5,6‐trimethyl‐1,2,4‐trithian molecular ions adequately accounts for all major fragmentations of the former. These fragmentations are losses of C 4 H 8 , C 2 H 4 S, S 2 H˙, C 4 H 8 S and C 2 H 4 S 2 . Similar rearrangements are proposed for other 1,3,5‐trithans and 1,3‐dithians.
