Thiocarbonylcompounds such as 1a, 1b, 1c, 1d, 1e and 1f were prepared and irradiated with UV-light in hexane solution.The products obtained in this photolyses are 3a, 3b and 3c.Only 3c dissociates in the temperature range 140-190 deg C reversible to 2c.The others, 3a and 3b, decompose yielding bis(trifluoromethyl)diselenide, 6b and 6d, without forming the corresponding methyl radical 2a and 2b.This was proved by spin-trapping experiments utilizing phenyl-t-butylnitrone.Attempts to prepare 3e were unsuccessful but led to the new compounds 7a, 7b, 7c, 1,1,1-tris(trifluoromethylseleno)ethan (7d) and, surprisingly, 9.Physical and spectroscopic data of the newly prepared substances are provided.
