SYNTHESIS OF NEW MONO-FUNCTIONALISED TETRATHIAFULVALENE DERIVATIVES BY REACTIONS OF TETRATHIAFULVALENYLLITHIUM WITH ALDEHYDES AND KETONES - X-RAY CRYSTAL STRUCTURES OF TTF-CME(OH)FC, TTF-CME(OME)FC AND TTF-CH(OME)TTF (FC = FERROCENYL)

摘要

Reactions of tetrathiafulvalenyllithium (TTF-Li) with a range of aldehydes and ketones have been explored for the first time, to provide an efficient route to mono-functionalised TTF derivatives of general formulae TTF-CH(OH)R (R = alkyl, phenyl, tetrathiafulvalenyl and ferrocenyl) and TTF-CR(OH)R' (R = alkyl, phenyl R' = alkyl, phenyl, tetrathiafulvalenyl, ferrocenyl and R-R' = fluorenyl). Subsequent transformations involving the reactive alcohol group of some of these compounds are reported. The structures of the three title compounds have been established by single-crystal X-ray analysis. (C) 1997 Elsevier Science Ltd. [References: 47]
