a 20 ml reaction vessel under vigorous stirring. The reaction was
conducted at 308 K for a specific period of time. The reaction was
monitored by taking out aliquots of the reaction mixture at specific time
intervals, diluting them with a known quantity of diethyl ether, separating
the catalyst and injecting the diluted liquids to a Shimadzu GC-2010
Detector-Mass spectrometer (GC-MS-QP2010S), fitted with AOC-20i
Auto Injector and ZB-5MS column (30 m × 0.25 mm × 0.25 μm). The
column oven and injection temperature were set at 60 and 250 °C,
respectively. The column temperature was increased from 60 to 260 °C
using a ramp rate of 15 °C/min and held at 260 °C for 4 min. The GC
peaks were identified by comparing the obtained retention times with
known standard solutions using a Shimadzu GC-MS QP2010S equipped
with GC-MS detector. The products were also purified using column
chromatography (eluent: petroleum ether-ethyl acetate mixture) and
