    • Although there is evident broadening of lines with the use of an equivalent amount of copper(I) hexafluorophosphate, the chemical shift of allylic, phenyl, acetyl, and benzylic hydrogens change less than 0.05 ppm. However, the ether ethylene hydrogens, originally compacted in the region 3.60-3.72 ppm, are spread from 3.6 to 4.20 ppm. In contrast, the complex with sodium tetraphenylborate produces a decrease in the chemical shift for ether hydrogens to 3.18-3.70; the allylic methylene group shifted from 4.05 to 3.95 ppm; and phenyl, acetyl, and benzylic hydrogens were only modestly affected.
