In a new process for the prodn. of carbonyl psuedohalides of the formula SCN-CO-Y (I) (where Y is isothiocyanate or isocyanato), a carbonyl halide of the formula Hal(1)-CO-Hal (2) (II) (where Hal(1) and Hal(2) are F, Cl or Br and Hal (2) can also be isocyanato) is reacted with ammonium thiocyanate in the presence of an inert polar diluent at below 30 deg.C in such a way that the carbonyl halide (II) is always present in excess. The cpd. isothiocyanate-carbonyl isocyanate (Ia) of the formula SCN-CO-NCO is new and claimed. Also new and claimed is the use of carbonyl diisothiocyanate (Ib) for the prodn. of 5,6-dihydro-6-thioxo -2-(XR1)-1,3,5- thiodiazin-4-one derivs. (II) (where X is O, S or NR2; and R1 and R2 are H, open-chain or cyclic alkyl, aralkyl or aryl) and of 2-thiobuirsts of the formula (R3) (R4)-CO-NH-CS-N(R3)(R4) (III) (where R3 and R4 are H, alkyl, aralkyl or aryl or N(R3) (R4) is a heterocyclic ring). (I) are reactive substances suitable for use as intermediates e.g. pharmaceuticals ...

In a new process for the prodn. of carbonyl-thiocarbonyl-amine derivs. ACONHSCB (I) a 1,3,5-thiadiazine deriv. (II) is reacted with an active hydrogen cpd. R7-XH (III), possibly with simultaneous elimination of HSCN, in the presence of an inert solvent at ca 0-150 deg.C (where A is -YR4 or -NH-CS-YR6; Y is O, S or NR5; R4 is alkyl, aralkyl or aryl or, when Y is NR5, also H; R5 is H, alkyl, aralkyl or aryl; R6 is aryl; B is XR3; X is O, S or NR2; R3 is alkyl, aralkyl or aryl or when X is NR2, also H; or -XR3 is morpholino, piperidino, piperazino or thiomorpholino; R2 is H, alkylaralkyl or aryl; or A and B are each morpholino, piperidino, piperazino or thiomorpholine; or A and B together form a residue -NR8-CS-NH- in which R8 is aralkyl or aryl; and R7 is R4 and R6, or -YR7 is morpholine, piperazino, piperidino or thiomorpholino; or, when X is NH, -YR7 is an N-R3-N- (5,6-dihydro-4-oxo-6- thioxo-4H-1,3,5 thiodiazin-2-yl) amino residue).

New 1,2,5-thiadiazine derivs. are cpds. of formula (I). (where R1 is H, open-chain or cyclic alkyl, aralkyl or aryl; and X is O, S or NR2, R2 being H, open-chain or cyclic alkyl, aralkyl or aryl). Prodn. of (I) comprises reaction of SCN-CO-NSC with R1-XH. The reaction is carried out in the presence of an inert solvent at ca 0-30 deg.C. (I) are useful as pharmaceuticals, microbicides, fungicides andinsecticides. They are also useful as reactive intermediates in particular, cpds. (I) in which R1 is alkyl, aralkyl or aryl or, when X is NR2, also H may be used for the preparation of carbonyl-thiocarbonyl-amine cpds. of the formula A-CO-NH-SC-B (where A is -Y-R4 or -NH-Y-R6; Y is O, S or NR5; R4 is alkyl, aralkyl or aryl or, when Y is NR5, also H; R5 is H; alkyl, aralkyl or aryl; R6 is aryl; B is XR3; R3 is alkyl, aralkyl or aryl or, when X is NR2, also H; R2 is H, alkyl, aralkyl or aryl; or A and B are each morpholino, piperidino, piperazino or thiomorpholino; or A and B together represent ...
