4. Characterization of the Product
GC – FID and GC-MS
The GC analysis was done with a GC from Agilent Technologies Inc. model 7890B with a flame ionization detector (FID, 325°C), a HP-column (length: 30m, ø: 0.25mm, film thickness: 0.25 μm)) and an auto sampler. N2 is used as carrier gas (v = 1.0 ml/min, 30 cm/s) with an injection volume 1 μL and a split of 15:1. An example of a typical GC chromatogram of the product solution is shown below. Conversion of substrate and yields were determined with dibutylether as internal standard by GLC.
NMR
The purified products were analysed with NMR. As spectrometer, a Brucer DRX600 (600 MHz) and CDCl3 as solvent was used. The reaction mixture was concentrated and purified by column chromatography (ethyl acetate 1:0 to 1:10).
