Abstract

Synthesis of Substituted Fluorenones and Substituted 3~,3f-Dichlorospiro[fluorene-9,2f-thiiranes ] ... Warren Chew, Rosemary C. Hynes, and David N. Harpp' Department of Chemistry, McCill University, Montreal, Quebec, Canada H3A 2K6 ... Several novel 9-fluorenones were synthesized and were used as precursors in an attempt to prepare unique substituted 3',3'-dichlorospiro[fluorene -9,2'-thiiranranea]. Several of the thiiranes were unstable and desulfurized during their ...
