Sn(OTf)2 is an efficient and versatile catalyst for the highly regioselective opening of styreneoxide with aromatic amines, which allowed for the preparation of fourteen 2-arylamino-2-phenylethanols, some of them described here for the first time (6g, 6i, 6j, 6k and 6m). Sn(OTf)2 also catalyses the opening of styreneoxide with aliphatic amines in moderate to high yields but with a lower degree of regioselectivity
