• Infrared spectra were recorded on either a Perkin-Elmer Model 1420 infrared spectrometer or a Nicolet MXS FT IR as thin films or nujol mulls. NMR spectra were obtained in CCl4, DCCl3, or Me2SO - d6 solutions [(CH3)4 Si internal standard)] at 60 MHz with a Varian EM-360 spectrometer. When NMR samples were run in D2O-DCl mixtures, DSS was the internal standard. The mass spectra were obtained on a Hitachi Perkin-Elmer RMU-6E spectrometer. All boiling points and melting points are uncorrected and melting points were recorded on a Fisher-Johns melting-point apparatus. Distillations were carried out in a Kugelrohr apparatus

• When pyridine derivatives and other potential water soluble substrates were used, the reaction mixture was diluted with a saturated aquous sodium chloride mixture to minimize loss of the products during extraction
