Nicole is50 ft ir spectrometer

All the chemicals were used as acquired. All of the chemicals consumed were purchased from an international chemical supplier. The melting point was determined using a Stuart Scientific SMP3, version 5.0, melting point equipment (Bibby Scientific Limited, Staffordshire, UK), which was reported as uncorrected, on a clean Thermo Scientific NICOLE iS50 FT-IR spectrometer (Madison, WI, USA). Using TMS as an internal standard, the ¹H, and ¹³C spectra were captured using Bruker 850 MHz equipment in a CDCl₃. Chemical shifts are displayed in ppm, while coupling constants are given in hertz. Aluminum sheets covered with silica gel (Type 60 GF254, Merck, Darmstadt, Germany) were used for TLC, and the spots were found by exposing the sheets to UV light at either 254 or 360 nanometers. A PerkinElmer 2400 Series II Elemental CHN analyzer was used to perform elemental analyses. MoKa (k = 0.71073A) radiation was used to collect the single crystal X-ray data set for 2a on the Bruker Kappa X8 APPEX II diffractometer. The scan area was 2.22° to 33.00°.
