実験手順

For example, 3,3'-dinitro-4,4'-dichlorobenzophenone can be prepared in a yield of 95 to 98% by nitrating 4,4'-dichlorobenzophenone [E. R. Kofanov et al., J. Org. Chem. USSR, 15, 98-100 (1979)]. 5,3'-Dinitro-2,4'-dichlorobenzophenone can be prepared in a high yield by nitrating 2,4'-dichlorobenzophenone [E. H. Faith et al., J. Am. Chem. Soc., 77, 543 (1955)]. 3,3'-Dinitro-4-chlorobenzophenone can be prepared in a high yield by nitrating 4-chlorobenzophenone [G. S. Mironov et al., J. Org. Chem. USSR, 8, 1538 (1972)]. 3,4'-Dinitro-4-chlorobenzophenone can be prepared by nitrating 4-halogeno-4'-nitrobenzophenone obtained by the condensation reaction between p-nitrobenzoyl chloride and chlorobenzene [P. T. Montagne et al., Ber., 49, 2267-2270 (1916); G. S. Mironov et al., J. Org. Chem. USSR, 8, 1538-1543 (1972)]. 3,3'-Dinitro-6,4'-dichlorobenzophenone can be prepared in a high yield by nitrating 2,4'-dichlorobenzophenone obtained by the condensation reaction between 2-chlorobenzoyl chloride and chlorobenzene [H. F. Faith et al., J. Am. Chem. Soc., 77, 543 (1955)].
