Rapid 2 xrd image plate

All reactions were performed under dry argon atmosphere with flame-dried glassware. All commercial reagents were ACS reagent grade and used without further purification. Dichloromethane was distilled from CaH₂ immediately prior to use. Melting points were determined in an open capillary tube with a Mel-temp II melting point apparatus. Infrared spectra were recorded on a Perkin-Elmer 1600 series FT-IR spectrophotometer, and peaks were reported in reciprocal centimeters (cm^–1). ¹H NMR spectra were recorded on a Varian Inova 500 and 300 MHz NMR spectrometer; ¹³C NMR spectra were recorded on Varian Inova 500 and Varian 300 MHz NMR spectrometers at 125 and 75 MHz, respectively. Chemical shifts are reported in parts per million (ppm). ¹H and ¹³C chemical shifts are referenced relative to tetramethylsilane. X-ray crystal analysis was performed by Rigaku RAPID II XRD Image Plate using graphite-monochromated MoKα radiation (λ = 0.71073 Å) at 173 K. (N-p-Tosylimino)phenyl-λ³-iodane 2a [41 (link)], (N-p-nosylimino)phenyl-λ³-iodane 2b [42 (link)], (N-o-nosylimino)phenyl-λ³-iodane 2c [43 (link)], and N-(phenylsulfonylimino)-phenyl-λ³-iodane 2d [44 (link)] were prepared according to the reported procedures.

All reactions were performed in
open air with a stopper and oven-dried glassware. All commercial reagents
were of ACS grade and were used without further purification. NMR
spectra were recorded using an Oxford 500 and 300 MHz and a Bruker
400 MHz NMR spectrophotometer (¹H NMR, ¹³C NMR,
and ¹⁹F NMR). Chemical shifts are reported in parts per
million (ppm). Melting points were determined in an open capillary
tube with a Mel-Temp II melting point apparatus. Infrared spectra
were recorded on a PerkinElmer Spectrum 1600 series FT-IR spectrometer.
X-ray crystal analysis was performed by Rigaku RAPID II XRD Image
Plate using graphite-monochromated Cu or Mo Kα radiation (λ
= 1.54187 or 0.71073 Å) at 125 or 173 K. See the CIF file for
more detailed crystallography information. 2′-Bromo-[1,1′-biphenyl]-2-amine 5 and 2′-chloro-[1,1′-biphenyl]-2-amine 6 were prepared according to the reported procedures.^2a
