Abstract

derivativesz0 of the ethanol samples showed well-resolved resonances corresponding to all four possible species carrying 3H in the methylenegroup (Figure 1, Table I).(R)-[1-ZHl, 1- 3HlJEthane gave predominantly (S)-[1-2Hl, 1-3Hl]-and (R)-[l-3Hl] ethanol, and conversely,(S)-[l-zHl, 1-3Hl] ethane afforded predominantly (R)-[1-zHl, l-3Hl]-and (5 ')-[l-3H,] ethanol. The results show that the hydroxylation of ethane proceeds with predominant ...
