The products of the gas‐phase pyrolysis of two regioisomeric 1,2,4‐trithiolane S ‐oxides were collected in an argon matrix at 10 K and studied by means of spectroscopic as well as computational methods. Whereas the main products of the pyrolysis of the “symmetrical” S ‐oxide were identified asthioformaldehyde S ‐oxide and thioformaldehyde S ‐sulfide, the “non‐symmetrical” S ‐oxide gave predominantly dithioformic acid, which exists as a mixture of s ‐ cis and s ‐ trans conformers. We present a rationalization of the reaction pathways including density functional theory computations.
