NMR

Treatment of 2-quinolinone with diethylaminetrimethylsilane was used to prepare the corresponding trimethylsilyl derivative (67). This was reacted with chloro(chlormethyl)dimethylsilane to give the chloro derivative, and with (bromomethyl(chloro)methyl- silane to give the bromo derivative. The chloro derivative was treated with antimony trifluoride to give the fluoro derivative, and with trimethylsilyl triflate to give the triflato derivative.

The x-ray crystal structure of these compounds was determined on a one circle diffractometer, equipped with an imaging plate system as detector (70). Graphite monochromated Mo-K radiation (-0.71073 ?) was used. Data collection was performed in a rotation mode. The raw intensity data
