✦ Synopsis
New 9-substituted 3-nitrofluorenes were prepared as potential intermediates in a study of modified electrophilicity and mutagenicity of the carcinogen 3-N,Odiacetylhydroxylaminofluorene. The reported derivatives, together with some already known 9-substituted 3-nitrofluorenes, were too unstable to survive the reducing conditions required to transform the nitro group to the corresponding hydroxylamine.
