New evidence for through-space transmission of substituent effects in benzene derivativesElectronic supplementary information (ESI) available: Table S1 containing literature data for substituent constants and pKa values used in this work. See http://www.rsc.org/suppdata/p2/b1/b106418e/

Electrostatic interaction energies between dipolar substituents and dipolar or charged reaction sites are re-examined. At short interaction distances and giv...
