Activation of hydrogen peroxide through hydrogen-bonding interaction with acidic alcohols: Epoxidation of alkenes in phenol
Wahlen, Joos,De Vos, Dirk E.,Jacobs, Pierre A.
, p. 1777 - 1780 (2003)
(Matrix presented) Electrophilic activation of hydrogen peroxide can be achieved in acidic alcohol solvents without the need for a metal catalyst. This concept is illustrated by the epoxidation of alkenes with H2O 2 employing phenol as a solvent. It is proposed that intermolecular hydrogen bonding between H2O2 and phenol activates H 2O2 for oxygen-atom transfer. In this interaction, the role of phenol is purely catalytic.

experimental part, p. 3433 - 3438 (2010/02/28)
Chemo- and stereoselectivity in the ring-opening reaction of epoxides with erbium(III) triflate are described. Epoxides can be cleaved under neutral conditions with alcohols and thiols in the presence of catalytic amounts of Lewis acid, affording the corresponding β-alkoxy alcohols and β-hydroxy sulfides in high yields. In water, epoxide ring opening occurs to produce the corresponding diols in good yields.
Bi(OTf)3-catalyzed regioselective ring opening of epoxides with phenols: Facile synthesis of 1,3-diaryloxy-2-propanols

, p. 1142 - 1143 (2007/10/03)
Substituted aryl oxiranes undergo the facile ring opening with phenols in the presence of catalytic amount of bismuth(III) triflate to afford 1,3-diaryloxy-2-propanols in excellent yields under mild conditions. Bismuth(III) triflate is relatively non-toxic, easy to handle and inexpensive, which makes this procedure particularly attractive for large scale synthesis. Copyright
