M. Lanfranchi et al., ORGANIC NITRO-COMPOUNDS AS LIGANDS - A COMPARISON BETWEEN THE LIGAND BEHAVIOR OF MENO2 AND PHNO2 TOWARDS ALCL3, Journal of the Chemical Society. Dalton transactions, (9), 1993, pp. 1463-1464
The crystal-structure analyses of the complexes [AlCl3(RNO2)] (R = Me
or Ph) and NM R data in solution suggest a stronger Al-O co-ordinative
interaction in the case of nitrobenzene compared to nitromethane; thi
s could account for the dramatic solvent effects observed during certa
in electrophilic acylation processes involving AlCl3 as a promoter.
