Abstract

cis-Dioxoruthenium (VI) complex [(Me3tacn)(CF3CO2) RuVIO2] ClO4 (1, Me3tacn= 1, 4, 7- trimethyl-1, 4, 7-triazacyclononane) reacted with alkenes in aqueous tert-butyl alcohol to afford cis-1, 2-diols in excellent yields under ambient conditions. When the reactions of 1 with alkenes were conducted in acetonitrile, oxidative CC cleavage reaction prevailed giving carbonyl products in> 90% yields without any cis-diol formation. The alkene cis- ...
