6.1.2 Mass Spectrometry
136
Chapter Six
Electron impact (EI) and fast atom bombardment (FAB) mass spectra were recorded on a
Kratos concept 1H, double focussing forward geometry mass spectrometer. 3-Nitrobenzyl
alcohol was used as the matrix for the FAB spectra. Electrospray mass spectra were
obtained on a Micromass Quatro LC.
6.1.3 Infrared Analysis
Infra red spectra were recorded on a Perkin Elmer FT-IR spectrometer at 4 cm -1 resolution
(16 scans) with a Universal ATR sampling accessory.
6.1.4 Elemental Analysis
All elemental analyses were performed by the Elemental Analysis Service at the London
Metropolitan University.
6.1.5 X-ray crystallography
X-ray crystallography data were collected on a Bruker Apex SMART 2000 diffractometer.
Crystal data and structure refinement can be found in the Appendix.
6.1.6 Starting Materials
Starting materials were used as received from Sigma Aldrich, Lancaster, Apollo,
Fluorochem, ABCR, Alfa Aesar, Acros organics or Strem. Where dried solvents were
necessary, dichloromethane, hexane, diethyl ether, tetrahydrofuran, and acetonitrile were
distilled using an Innovative Technology Pure Solv automated still. All dried solvents were
stored in sealed ampoules under an atmosphere of dry nitrogen over 4Å molecular sieves.
Pyridine was refluxed over calcium hydride and distilled into a dried ampoule under
nitrogen.
