Improved synthesis of diethyl ferrocenylphosphonate, crystal structure of (FcPO3Et2)2·ZnCl2, and electrochemistry of ferrocenylphosphonates, FcP(O)(OR)2, FcCH2P(O)(OR)2, 1,1′-fc[P(O)(OR)2]2 and [FcP(O)(OEt)2]2·ZnCl2 (Fc=(η5C5H5)Fe(η5C5H4), fc=(η5C5H4)Fe(η5C5H4), R=Et, H)

The preparation, spectroscopy, structure and electrochemistry of some [Co(η4-C4Ph4)(η5-C5H4R)] complexes

“…5 proved an excellent precursor for the triphenyl phosphonium salt [7]Cl, but it failed to react with P(OEt) 3 . The HornereWadswortheEmmons reagent 6 [25] was obtained in the same way as its ferrocene counterpart [26] by a modification of the basic Michaelis reaction [27] in which Na[P(O)(OEt) 2 ] is reacted with the alcohol 4. [11].…”

Electroactive poly zinc, cadmium, manganese ferrocenylphenylphosphinates

“…The transformation of the ester into the acid leads to a 65 mV decrease of the half wave potential. It is noteworthy that a greater effect has been observed for ferrocenylphosphonates [30], whereas it does not exist for carboxylate derivatives [41]. The neutralisation of the acid leads to a decrease of 162 mV of the half wave potential.…”

“…Ethyl ferrocenylphenylphosphinate was prepared by reaction of monolithioferrocene with chloroethyl phenylphosphonate (Scheme 2), which was obtained by chloration of ethyl phenylphosphinate PhP(O)(OEt)H prepared by ethanolysis of PhPCl 2 [29].The high yield, after purification by chromatography, (88%) results from the use of a ''super base'' t BuLi/ t BuOK at À80°C as we have reported for the preparation of ferrocenylphosphonic acid [30].…”

Ferrocenylphosphonic acid: from molecule to electro-active hybrid materials

“…Ferrocenylphosphonic acid and zinc ferrocenylphosphonate Zn(HO 3 PFc)·2 H 2 O have been prepared as already reported [8,19].…”
