Notes:
The substituent effect on the proton hyperfine splitting constants (hfsc) of the charge-transfer complexes of Grignard reagents (RMgBr, R = CH3, C2H5, CH3CH=CH) with seven 3-substituted 9,10-phenanthroquinones is reported. A back-donation bonding interaction between phenanthrenesemiquinonate anion radical π* and the magnesium p orbital is revealed by the hfsc analysis.
