We learned that to create vicinal diols from alkenes, the cis-1,2-diol or trans-1,2 diol required very different reagents. This isn't always the case and one notable reaction that defies this convention is the Prévost reaction! (4 points) To make the cis-diol, we typically use osmium tetroxide (catalytic amounts!). What other reagent combination would work for this particular transformation? a. OH OH (rac b. (4 points) To make the trans-diol, what reagent combination would be employed? ?? 1F2 OH (4 points)...
