Abstract
Treatment of 9-fluorenyllithium with acetyl chloride produces 9-acetylfluor ene, (I), and several by-products, among which is `diacetylfluorene', now c haracterized definitively as 9-(1-acetoxyethylidene)fluorene [IUPAC name: ( 1-fluoren-9-ylidene)ethyl acetate], (II), C17H14O2, derived from acetylatio n of initially formed (I). Various parameters disclose substantial structur al distortion within (II) emanating from A ((1,3)) strain associated with t he 9-(acetoxyethylidenyl)fluorene system.
