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.
