syn-diacetoxylation of alkenes and 1,2-oxyacetoxylation of terminal alkynes has been developed using (diacetoxyiodo)benzene as oxidant. A broad range of internal and terminal alkenes, including electron-rich as well as electron-deficient alkenes, gave the desired products in good to excellent yields with high diastereoselectivity (up to >99:1 dr). In addition the high catalytic activity of ironcatalysis for the

Treatment of terminal alkynes with PhI(OAc)(2) in different acids at 70 degrees C provided the corresponding alpha-acyloxy ketones in good to excellent yields. A plausible mechanism has been proposed based on the experimental results. (C) 2009 Elsevier Ltd. All rights reserved.
