All the chemicals were
purchased from Aldrich & Co. IR spectra were recorded using KBr
pellets (1% w/w) on a Perkin-Elmer Spectrum GX FT-IR spectrophotometer.
Electronic spectra were recorded on a Shimadzu UV 3101PC spectrophotometer.
Mass analyses were performed using the positive and negative ion spray
ionization technique on a Waters Q Tof-micro mass spectrometer for
all these complexes upon dissolving in methanol–water solvents.
CHNS analyses were done using a Perkin-Elmer 2400 CHNS/O analyzer.
Single crystal structures were determined using a BRUKER SMART APEX
(CCD) diffractometer. 1H and 13C NMR spectra
were recorded on a Bruker Avance II 500 MHz or Jeol 600 MHz FT-NMR
spectrometer. Chemical shifts for proton resonances are reported in
ppm (δ) relative to tetramethylsilane, and 13C spectra
are calibrated with reference to DMSO-d6. All the catalytic
products were established based on 1H NMR spectra. The
100 mL high-pressure catalytic reactor was from AMAR equipment.
