The fungicidal compds.[I; R1 = (un)substituted aliph., cycloalkyl, aryl, or aralkyl, (un)substituted NH2 or N heterocycle; R2 = H, CN, alkoxycarbonyl, acyl; R3 = CN, alkoxycarbonyl, acyl, alkyl- or arylsulfonyl, (un)substituted CONH2 or CSNH2 were prepd. by the reaction of R2R3CHCSNHR with (F3CH:CF)2[II in the presence of a fluoride acceptor. Thus, MeCOCH2CSNHPh and NaF were suspended in Me2CO, followed by the addn. of II to give 84 % I (R1 = Ph, R2 = H, R3 = COMe), which had fungicidal activity against Pyricularia oryzae.
