Mono- and diferrocenyl complexes with electron-accepting moieties formed by the reaction of ferrocenylalkynes with tetracyanoethylene

Further solvent-free reactions of ferrocenylaldehydes: Synthesis of 1,1′-ferrocenyldiimines and ferrocenylacrylonitriles

“…This difference in bond lengths is not observed in the comparable molecules 1-ferrocenyl-1-phenyl-2-(4-cyanophenyl)ethylene [15] and 2-ferrocenyl-1-(4-(trifluoromethyl)phenyl)propene [15], where the substituent on the ethylene group is not nitrile. A similar difference was observed in the molecule, 2,5-dicyano-3-diferrocenylhexa-2,4-dienedinitrile [16]. In contrast to 16, molecules of compound 17 have the nitrile-ethylene and cyano-phenyl moieties twisted out of the plane of the ferrocenyl C p ring.…”

Synthesis, structures and some reactions of Ru(CCCCFc)(PP)Cp (PP=dppm, dppe) and related compounds

“…), presumably because of their rapid transformation to the butadienyls. Recently, similar reactions between tcne and ethynylferrocene, diferrocenylethyne and 1,4-diferrocenylbuta-1,3-diyne to give the corresponding substituted s-cis-butadienes have been described [21].…”

“…5). TCNQ itself shows two reversible reductions at 0.21 and À0.33 V (vs. SCE) [42]. In contrast 4a, chosen as typical of other 4, shows a quasi reversible oxidation at ca.…”
