Article abstract of DOI:10.1016/0022-328X(93)83111-8

The influence of nitro and chromiumtricarbonyl groups on susceptibility of stilbene and 4,4'-dimethoxystilbene to protophilic isotope hydrogen exchange were compared.Both groups assist in the reaction, but for the chromiumtricarbonyl substituent the simul
