Article abstract of DOI:10.1016/S0040-4039(01)91164-5

The element effects for the substitution of tricyanovinyl chloride and bromide by the p-position of three dialkylanilines are k_Br/k_Cl=2.37+/-0.18.An early transition state for the expulsion of the halide ion from the intermediate zwitterion is indicated.
