Their photochemical and electrochemical properties before and after addition of an organic acid are investigated, indicating that these complexes are sensitive to external perturbation of protonation, leading the structural change to an expansion of π-conjugated system by cyclocondensation reaction and promoting intramolecular electron transfer from donor to acceptor. They would be good candidates for studies of novel SAMs, and the properties triggered by protonation-induced intramolecular electron transfer will make the SAMs be useful in designing new functional molecular devices. http://www.mdpi.com/1420-3049/15/1/150/ Mon, 04 Jan 2010 00:00:00 CET Molecules 2010-01-04 15 1 Article 150 163 1420-3049 Thioacetyl-Terminated Ferrocene-Anthraquinone Conjugates: Synthesis, Photo- and Electrochemical Properties Triggered by Protonation-Induced Intramolecular Electron Transfer 2010-01-04 doi: 10.3390/molecules15010150 Wen-Wei Zhang Mio Kondo Takako Fujita Kosuke Namiki Masaki Murata Hiroshi Nishihara http://www.mdpi.com/1420-3049/14/11/4747/ Since the serendipitous discovery of ferrocene by Pauson and Kealy in 1951, it has become one of the most important structures in Organic Chemistry. Lately, kinetic resolution has emerged as a useful tool for the synthesis of planar chiral ferrocenes. This review aims to cover and discuss the development of this topic. http://www.mdpi.com/1420-3049/14/11/4747/ Fri, 20 Nov 2009 00:00:00 CET Molecules 2009-11-20 14 11 Review 4747 4757 1420-3049 Kinetic Resolution: A Powerful Tool for the Synthesis of Planar-Chiral Ferrocenes 2009-11-20 doi: 10.3390/molecules14114747 Andrea-Nekane R. Alba Ramon Rios http://www.mdpi.com/1420-3049/14/11/4312/ The C2-symmetrical “salen” ligand (+)-9 bearing two [5]ferrocenophane substituents has been prepared in five steps starting from readily available diacetylferrocene, p-hydroxybenzaldehyde and (R,R)-N,N’-diphenylethylenediamine. Reaction of (+)-9 with Mn(OAc)3, Co(OAc)2 ZnEt2 or UO2(OAc)2 gave the corresponding metal-complexes which were characterised by spectroscopic methods. http://www.mdpi.com/1420-3049/14/11/4312/ Mon, 26 Oct 2009 00:00:00 CET Molecules 2009-10-26 14 11 Article 4312 4325 1420-3049 Synthesis and Characterization of Some Chiral Metal-Salen Complexes Bearing a Ferrocenophane Substituent 2009-10-26 doi: 10.3390/molecules14114312 Angela Patti Sonia Pedotti Francesco Paolo Ballistreri Giuseppe Trusso Sfrazzetto http://www.mdpi.com/1420-3049/14/9/3161/ 3-Cyanoamino-1,2- and -2,3-diferrocenylcyclopropenes 6a,b and 11a,b prepared by the reaction of diferrocenylcyclopropenylium salts with sodium cyanamide undergo smooth intramolecular transformations with both conservation of the three-membered ring [affording 3-cyanoimino-1,2-diferrocenylcyclopropene (8)] and its opening [affording Z-3-morpholino- and Z-3-piperidino-3-(cyanoimino)-1,2-diferrocenylprop-1-enes 7a,b and Z-3-cyanoimino-2,3-diferrocenyl-1-methylthioprop-1-ene (10)]. 3-Cyano-imino-1,2-diferrocenylcyclopropene (8) reacts with hydrazine to form 3-amino-6-ferrocenyl-5-ferrocenylmethyl-1,2,4-triazine (12) and Z-2,3-diferrocenylacrylohydrazide N-cyanoimide (13) as a result of intramolecular transformations. The structures of the compounds obtained were determined by IR, 1H- and 13C-NMR spectroscopy and mass spectrometry. The structures of compounds 7a and 10 were additionally confirmed by their X-ray diffraction analysis data. http://www.mdpi.com/1420-3049/14/9/3161/ Wed, 26 Aug 2009 00:00:00 CEST Molecules 2009-08-26 14 9 Article 3161 3175 1420-3049 Intramolecular Transformations of 3-Cyanoamino- and 3-Cyanoimino-1,2-diferrocenylcyclopropenes 2009-08-26 doi: 10.3390/molecules14093161 Elena Ivanovna Klimova Tatiana Klimova Marcos Flores-Alamo Leon Vladimirovich Backinowsky Marcos Martinez Garcia
