Organic Name Reactions on Instagram: "The Upjohn dihydroxylation converts alkenes into syn-1,2-diols using catalytic osmium tetroxide with a stoichiometric co-oxidant. The reaction proceeds through a cyclic osmate ester formed by concerted [3+2] cycloaddition, followed by hydrolytic cleavage to release the vicinal diol. The reduced osmium species is then reoxidized by the stoichiometric oxidant to regenerate the active Os(VIII) catalyst, closing the catalytic cycle. Early studies at Upjohn Compa
