New (pyrimido[4,5-e][1,3,4]thiadiazin-7-yl)hydrazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates as bidentate nucleophiles with 5-bromo-2,4-dichloro-6-methylpyrimidine as an electrophile and further replacement of chlorine atom on the seven number position of pyrimido[4,5-e][1,3,4]thiadiazin by hydrazine in boiling ethanol.
New 3-alkylsulfanyl-7-chloro-5-methyl-1-phenyl-1H-pyrimido[4,5-e][1,3,4]thiadiazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates with 5-bromo-2,4-dichloro-6-methylpyrimidine in basic acetonitrile.

The synthesis of some new 3-(alkylthio)-1-phenyl-1H-[1, 3, 4]thiadiazino[5, 6-b]quinoxalines4 have been achieved by cyclocondensation reaction of the alkyl-2-phenylhydrazinecarbodithioates 1 with 2,3-dichloroquinoxaline 2 in basic N,N-dimethylformamide.
Dithiolene-like platinum and nickel complexes of benzyl 3-phenyl and 3-(4′-nitro) phenyl dithiocarbazate and of (4′-nitro) benzyl 3-phenyl and 3-(4′-nitro) benzyldithiocarbazate
The spectroscopic and electrochemical properties of the complexes [MNRNC(S)SR′}2] (M=Ni or Pt; R=C6H5 or C6H4NO2-4; R′=CH2C6H5 or CH2(C6H4NO2-4) were investigated. The strong electron-attracting effect of nitro groups strongly influences their spectroscopic and electrochemical properties.
