摘要：

The formation of thiadiazolidines 3a‐c and dithiazolidines 4a‐c and 5a‐b from the title reactions has been studied in detail under a variety of conditions. On the basis of kinetic measurements, isomerization studies and cross experiments a mechanism is proposed involving path (b) (Scheme 1) as the first step, followed by a series of isomerizations as shown in Scheme 3.
