Nonetheless, on page 1168 of this issue, Wilson et al. (2) report the facile nucleophilic alkylation of benzene accomplished through highly reactive alkylcalcium nucleophiles. (science.sciencemag.org)
Because «like species repel,» electron - rich species should not react with other electron - rich species, so benzene should never undergo direct nucleophilic alkylation. (science.sciencemag.org)
It usually refers to the high - octane product from alkylation units. (eia.gov)
