1. The salt (II) was prepared in situ from the hydroxylamine (CF3)2NOH and powdered sodium hydroxide in THF in the presence of a molecular sieve to remove water.
2. R.E. Banks, C.M. Irvin, and A.E. Tipping, unpublished results.
3. The salt (II) as used both in the halogen-displacement reactions described in reference 6 and in the present work, was prepared by treatment of the parent hydroxylamine with sodium hydride in diethyl ether followed by removal of the ether by evaporation and then redissolution of the solid salt in the appropriate solvent, a method pioneered by R.E. Banks and R.A. Hughes in this Department.
