Air-sensitive reactions are done under a nitrogen atmosphere using Schlenk techniques. Flash column chromatography was carried out using silica gel (Silia-P from Silicycle, 60 Å, 40-63 µm). Analytical thinlayer-chromatography (TLC) was performed with silica plates with aluminum backings (250 µm with F-254 indicator). TLC visualization was accomplished by use of a 254/365 nm UV lamp. 1 H and 13 C and NMR spectra were recorded on a Bruker Advance spectrometer (400 or 500 MHz for 1 H and 100 or 125 MHz for 13 C). The following abbreviations have been used for multiplicity assignments: "s" for singlet, "d" for doublet, "t" for triplet, "dd" for doublet of doublets, "td" for triplet of doublets and "m" for multiplet. Deuterated acetone (acetone-d6), chloroform (CDCl3) and DMSO (DMSO-d6) were used as the solvents of recording NMR. H NMR spectra were referenced to the corresponding solvent peak. HPLC analysis was conducted on a Shimadzu Nexara series HPLC system. HPLC traces were performed using an ACE Excel 2 C18 (3µm C18, 3.0 × 150 mm) analytical reverse phase column using a methanol-water mobile phase. GCMS analysis were carried out in a QP2010SE system. Melting points were measured using open-ended capillaries on a melting point apparatus IA9200 and are uncorrected. High-resolution mass spectrometry (HRMS) was performed by the Mass spectrometry facility, University of St Andrews. Elemental analysis were performed using the facility of London Metropolitan University. Thermogravimetric analysis. Analysis was carried out by heating the sample from 25 °C to 700 °C.
