2.1.2 Instrumentation
Shimadzu Analytical (Shimadzu, ATX224) electronic balance has been used for weighing purpose and 400 MHz NMR spectrometer JEOL JNM-ECS has been used for the characterization of the epoxides. 1H NMR (JEOL JNM-ECS) spectra were recorded on 400 MHz on TH5 probe and are reported in parts per million (δ ) downfield relative to Me4Si as internal standard and 13C NMR spectra were recorded at 100 MHz and assigned in parts per million (δ ) relative to internal internal standard Me4Si.
