THIOCARBONYL DICHLORIDE (463-71-8) Reacts with water, decomposing to hydrochloric acid and sulfur dioxide, carbon disulfide, and carbon dioxide. Aqueous solution is incompatible with sulfuric acid, alkalis, ammonia, aliphatic amines, alkanolamines, alkylene oxides, amides, epichlorohydrin, organic anhydrides, isocyanates, vinyl acetate. Corrodes most metals in the presence of moisture. [Pg.1145]

Olefinations. Reaction of carbonyl compounds with gem-dichlorides in the presence of Zn-MCjSiCl provides alkenes. Reformatsky reaction on thiocarbonyl compounds also gives conjugated esters. [Pg.436]

Bis(thiocarbonyl)hydrazide derivatives of galactaric acid (186,187) have been prepared by reaction of 2,3,4,5-tetra-Oacetyl-D-galactaroyl dichloride (185) with 4-arylthiosemicarbazides335 or S-methyl(benzyl) hy-drazinecarbodithioates336 (Scheme 56). The adducts were subsequently converted into a variety of bis(heterocyclic) compounds including thiadia-zole, triazole, and oxadiazole derivatives. The tetraacetates 186 have been... [Pg.99]
