ABSTRACT:
The invention relates to a thiadiazole derivative of the formula I: ##STR1## in which Y is O, S, CH.sub.2, SO or a direct bond; m is 0 to 4 and n is 1 to 4 provided that when Y is S, O or SO m is 1 to 4, and when Y is O or SO n is 2 to 4; R.sup.1 is H or (C.sub.1-10)alkyl; A is 3,4-dioxocyclobuten-1,2-diyl or C.dbd.Z in which Z is O, S, NCN, NNO.sub.2, CHNO.sub.2, NCONH.sub.2, C(CN).sub.2, NCOR.sup.2, NCO.sub.2 R.sup.2, NSO.sub.2 R.sup.2 or NR.sup.3 in which R.sup.2 is (C.sub.1-6)alkyl or (C.sub.6-12)aryl and R.sup.3 is H or (C.sub.1-6)alkyl; B is (C.sub.1-6)alkoxy, (C.sub.1-6)alkylthio or NR.sup.4 R.sup.5 in which R.sup.4 and R.sup.5 are independently H, (C.sub.1-10)alkyl, C.sub.3-6 (alkenyl), (C.sub.3-6)alkynyl, (C.sub.2-6)(primary hydroxy)alkyl, (C.sub.2-6)(primary amino)alkyl or (C.sub.3-6)cycloalkyl or R.sup.4 and R.sup.5 are joined to form a 5- or 6- membered saturated ring optionally containing an additional O or NH: and the salts thereof.
