The microwave-assisted syntheses were performed using an Initiator EXP Microwave Biotage instrument (frequency of irradiation: 2.45 GHz). Analytical silica gel plates (Merck F254, Kenilworth, NJ, USA), preparative silica gel plates (Merck F254, 2 mm), and silica gel 60 (Merck, 70–230 mesh) were used for analytical and preparative TLC, and for column chromatography, respectively. All melting points were determined on a Gallenkamp melting point apparatus and are uncorrected. Elemental analyses were performed with a FlashE1112 Thermofinnigan elemental analyzer for C, H, N and the results were within ±0.4% of the theoretical values. All final compounds revealed a purity not less than 95%. Compounds were named following IUPAC rules as applied by ChemDrawUltra 9.0. The IR spectra were recorded with a Perkin-Elmer Spectrum RX I spectrometer in Nujol mulls and are expressed in cm−1. NMR spectra were recorded on a Bruker Avance 400 spectrometer (400 MHz for 1H-NMR and 100 MHz for 13C-NMR). The chemical shifts are reported in δ (ppm) and are relative to the central peak of the solvent which was CDCl3 or DMSOd6. The following abbreviations are used: s: Singlet, d: Doublet, t: Triplet, m: Multiplet, br: Broad, and ar: Aromatic protons.

The syntheses and manipulations described below were conducted under argon with rigorous exclusion of oxygen and water using a glove box, vacuum line, and Schlenk techniques. Hexane and toluene were purged with UHP grade argon (Airgas), passed through columns containing Q-5 and molecular sieves, stored over K mirrors and degassed before use. C6D6 (Cambridge Isotope Laboratories) was refluxed over K, degassed by three freeze–pump–thaw cycles, and vacuum-transferred before use. [Fe(Cp)2][PF6] and 1 3 were prepared according to literature procedures. The 1H (400 or 500 MHz), 13C{1H} (125 or 100 MHz), 29Si{1H} (99 or 80 MHz) and 19F (376 MHz) NMR spectra were obtained using a Bruker AV III HD 400 with a 5 mm BBO Prodigy probe or a Bruker AV III HD 500 with a 5 mm BBO Prodigy probe spectrometer and were referenced to SiMe4 (1H, 13C, and 29Si) or C7H5F3/CDCl3 (19F). Solution magnetic susceptibilities were determined by the Evans method.27 The FTIR samples were prepared as Nujol mulls in KBr discs using a PerkinElmer Spectrum RX1 spectrometer. Elemental analyses were performed either by using a PerkinElmer 2400 series II CHNS elemental analyser or with the assistance of Mrs. Anne Davies and Mr. Martin Jennings at The University of Manchester, UK.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
