Abstract:	The light and metal catalysed rearrangement of 3,4-disubstituted-Δ²-1,2,4-oxadiazolin-5-thiones (3) to the corresponding Δ²-1,2,4-thiodiazolin-5-ones (4) is described. The thermal stability of (3) is in great great contrast to the ease of rearrangement of the acyclic analogues. The rearrangement of (3) and (4) under electron impact are described.
