## Abstract Double asymmetric dihydroxylation of 1,5βhexadiene gave in one step a mixture of the __d,l__/__meso__ tetrols 6 in a ratio of 3.4:1. From this ratio a facial selectivity of 6.65:1 for each double bond can be calculated. As a consequence of the double reaction the __d/l__ ratio can be es
## Synopsis Poly(l,5-hexadiene) was prepared and its structure characterized by high-field I3C nuclear magnetic resonance. The polymer was shown to contain repeating five-membered rings separated by methylene bridges, with both cis and truns placements present in a 54 : 46 ratio. The result is com
