Substituted aryl oxiranes undergo the facileringopening 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(lll) triflate is relatively nontoxic, easy to handle and inexpensive, which makes this procedure particularly attractive for large scale synthesis.
