The flash-vacuumpyrolysis of selected dispirodicycloaliphatic 1,2,4-trithiolanes was studied by using matrix isolation techniques. The formation of thiosulfines and dithiiranes along with the corresponding thioketones was detected spectroscopically and confirmed by comparison with computed spectra. In the case of tetramethylcyclobutanone 1,2,4-trithiolane, the thermal formation of the dithiolactone

Preferential yield of ring expansion and rearrangement products through α-cleavage of tetramethyl-3-thio-1,3-cyclobutanedione (1) and 3-mercapto-2,2,4-trimethyl-3-pentenoic acid β-(thio lactone) (2) involving diradical and carbene has been observed upon photolysis of 1 and 2.
