The red-violet trifluoromethylselenocarbonylfluoride SeC(F)CF3 (1) is produced quantitatively by thermal 1,2-elimination of Me3SnF from trimethylstannylpentafluoroethylselane Me3SnSeC2F5 (2) at 300°C and 10−2 torr. 1 is less inert than the related selenocarbonyldifluoride SeCF2 and shows a strong dienophilicity. The reactions of 1 with 2,3-dimethyl-1,3-butadiene, isoprene, cyclopentadiene, penta
