Formation of multifunctional ligands by nucleophilic addition of alcohols and thiols to the alkyne groups in compound C5H5FeC5H4CCSCCH: Reactivity studies

“…The ferrocenyl group shows an almost-perfect eclipsed geometry with its rings. Similar features have been observed in related structures of [C 5 H 5 FeC 5 H 4 (C"CC 6 H 4 ) 2 SMe] [14] and [C 5 H 5 FeC 5 H 4 C"C(C 4 -H 2 S) 3 C"CC 5 H 4 FeC 5 H 5 ] [15].…”

“…According to the mechanisms described for these authors, we agree that once the complex [{Co 2 (CO) 6 } 2 (l-g 2 :g 2 -FcCCSCCH)] is formed, it can react with a molecule of the alkyne [{Co 2 (CO) 6 }(l-g 2 -FcCCSC"CH)] followed by another molecule of the ferrocenyl alkyne [{Co 2 (CO) 6 }(l-g 2 -FcC"CSCCH)] to give the trimerization product [{Co 2 (CO) 6 } 3 -(l-g 2 -FcCCS) 2 (l-g 2 -HCCS)]C 6 H 2 Fc after demetallation. Its spectroscopic and spectrometric data are the following: IR (m CO 2092m, 2061 s, 2030 vs), 1 H NMR {7.19 (s, 2H, C 6 H 2 ), 6.77 (s, 1H, HC"C), 4.54-4.36 (m, 12H, C 5 H 4 ), 4.34 (s, 5H, C 5 H 5 ), 4.31 (s, 5H, C 5 H 5 ), 4.20 (s, 5H, C 5 H 5 }, MS(ESI + ) m/z: 1488-1152 (M + ÀnCO, n = [6][7][8][9][10][11][12][13][14][15][16][17][18].…”

Rapid-scan time-resolved FT-IR spectroelectrochemistry – Study on the electron transfer of ferrocene-substituted thiophenes

“…Thiophene derivatives show great optical and electronic properties, and several studies of ferrocenyl complexes containing thiophene ring have been carried out [8][9][10][11]. In the literature [8,12], CV and Osteryoung square waver voltammetry (OSWV) were used to evaluate the redox properties, the degree of interaction and the possibility of ''electronic communication" among the ferrocene centers.…”

The synthesis and electrochemical behavior of 1,4-di-(2,5-dimethylazaferrocenyl)-1,3-butadiyne

“…Chemical shifts are reported in d (ppm) using CDCl 3 ( 1 H d 7.26 ppm) as the reference solvents. Mass spectra were recorded using EI methods on a micromass Autospec Q spectrometer.…”

“…) has been recognized as a stable, versatile redox active capping group. For example, 1 has been used as a terminal group in hetero nuclear Ru containing complexes [1,2], homo binuclear complexes with aromatic spacer groups [3], optically active polymers [4] and mononuclear oligo(phenylethynyl) molecular wires [5].…”
