WebOct 11, 2024 · Dichloroacetylene is a nonpolar compound. 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 of latent herpes virus by the toxic insult ( Cavanagh and Buxton 1989 ).

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.
