All of
the starting materials and solvents
were supplied from Merck, Acros, and Sigma-Aldrich chemical companies.
The chemicals and solvents were used in this study without further
purification. To record the 1H NMR and 13C NMR
spectra, a Brucker (250 MHz) Avance DRX was used. Pure deuterated
DMSO-d6 and CDCl3 were used
as solvents and tetramethylsilane as an internal standard. Chemical
shifts were reported in ppm (δ) and coupling constants in Hz
(J). To characterize the catalyst and also synthetic compounds with
FT-IR spectroscopy, a Shimadzu FT-IR 8300 spectrophotometer was employed.
The scanning electron micrograph (SEM) for the catalyst was obtained
using XL-30 FEG SEM, Philips, at 20 kV. Inductively coupled plasma
(ICP) analysis was carried out using an analyzer (Varian, Vista-Pro).
The melting points were determined in open capillary tubes in a Buchi
melting point B-545. The progress of the reactions was monitored by
thin layer chromatography (TLC) on silica gel PolyGram SILG/UV254
plates. Also, to purify synthetic compounds, column chromatography
was employed using columns charged with silica gel 60 (70–230
mesh) mesh.
