TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The catalyst is potassium hydroxide, sodium hydroxide, cesium hydroxide, ammonium hydroxide or tetraalkylammonium, Amberlyst A26OH (RTM: Basic polymer resins), a rehydrated hydrotalcite or basic ionic liquid, preferably sodium hydroxide. The catalyst is present at 0.2-20 mole%, preferably 2 mole%.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The primary or secondary amine has a structure of formula (R1-CH-OH-CH2-OH) (II). The cyclic carbonate has a structure of formula (IV). The DTGC is of formula (R1-C(OH)-CH2-S-C-(S)-NR2R3) (I). The five-membered cyclic carbonate is glycerol carbonate, propylene carbonate, ethylene carbonate or glycerol monocarbonate. The solvent of the reaction medium is a glycerol type polyol. The amine is secondary amine, preferably diethylamine, dimethylamine, dipropylamine, diisopropylamine, piperdine, diethanolamine or aniline. The carbonate is diethylcarbonate. The glycerol type polyol is glycerol, 1,2-propane diol, or ethylene glycol.R1 = 1-22C alkyl or 3-16C cycloalkyl (optionally substituted by one or more OH, -O-alkyl, thiohydroxy or -S-alkyl, where the alkyl chain may be interrupted by one or more heteroatoms of O, N or S), H, mono or poly unsaturated 2-22C alkenyl, 2-6C alkynyl, 6-10C aryl or 7-22C arylalkyl; and eitherR2, R3 = 1-22C alkyl or 3-16C cycloalkyl (optionally substituted by one or more OH, -O-alkyl, thiohydroxy or -S-alkyl, where the alkyl chain may be interrupted by one or more heteroatoms of O, N or S), H, mono or poly unsaturated 2-22C alkenyl, 2-6C alkynyl, 6-16C aryl or 7-22C arylalkyl; orNR2R3 = to form cycloamino group. ACTIVITY - Fungicide; Cytostatic.    MECHANISM OF ACTION - None given.    SPECIFIC COMPOUNDS - Preparation of 11 compounds (I) is disclosed e.g. 2,3-dihydroxypropyl diethyldithiocarbamate, 2,3-dihydroxypropyl piperidine-1-carbodithioate of formula (Ia), 2,3-dihydroxypropyl dibutyldithiocarbamate, 2-hydroxypropyl piperidine-1-carbodithioate and 2-hydroxypropyl diisopropyldithiocarbamate.    EXAMPLE - Propane-1,2,3-triol (84.5 mmole) was mixed with diethyl carbonate (16.9 mmole) in the presence of 2 mole% of sodium hydroxide during this stage; ethanol was continuously distilled and recovered. After 1 hour of reaction at 130 degrees C, carbon disulfide (16.9 mmole) and diethyl amine (16.9 mmole) were added to the medium which was stirred at 60 degrees C to give 2,3-dihydroxypropyl diethyldithiocarbamate.
