Abstract

All materials were of commercial origin. The 65% HI was obtained from Fluka; 43% HI is 65% HI that has been diluted with an equal volume of water.'H and 13C NMR spectra were recorded on Varian A-60A and XL-200 spectrometers, respectively. The initial reaction mixtures (1 mmol of formaldehyde as trioxane," 0.40 mL of solvent, other reagents as indicated in Table I) were sealed under vacuum in 4-mm id, 5-or 6-mm 0. d. Pyrex
