Dichloroacetylene
Dichloroacetylene (DCA) is an organochlorine compound with the formula C2Cl2. It is a colorless, explosive liquid that has a sweet and "disagreeable" odor. See more Dichloroacetylene was first synthesized in 1930. Ether solutions of dichloroacetylene are relatively stable, and such solution can be safely generated by dehydrochlorination of trichlorethylene. … See more Dichloroacetylene reacts with oxygen to give phosgene: ClC≡CCl + O2 → Cl2CO + CO Dichloroacetylene, being electrophilic, adds nucleophiles, such as amines: ClC≡CCl + R2NH → Cl(H)C=CCl(NR2) See more • Difluoroacetylene • Diiodoacetylene • Organochloride See more Dichloroacetylene causes neurological disorders, among other problems.

WebResults indicate that reductive β-elimination accounts for 87% of tetrachloroethylene (PCE), 97% of trichloroethylene (TCE), 94% of cis-dichloroethylene (cis-DCE), and 99% of trans-dichloroethylene (trans-DCE) reaction. Reaction of 1,1-DCE gives rise to ethylene, consistent with a reductive α-elimination pathway. WebDichloroacetylene is an exceptionally good substrate of microsomal GSTs (eqn [2]) and hence is a good precursor of the toxic cysteine S-conjugate DCVC (Reichert et al. 1976). Damage to the trigeminal nerve may be due to the toxic effects of DCVC or to activation …
