摘要：

(Chemical Equation Presented) Gently does it: The Pd-catalyzed oxidative cyclization of enynes with hydrogen peroxide, a simple, inexpensive, and environmental benign oxidant, is proposed to proceed through a catalytic Pd II/PdIV cycle in which the key C-Cl bond-forming step is the formation of a PdIV intermediate (see scheme). This is followed by a direct reductive elimination to generate C-Cl bonds with retention of the configuration of the C(sp3) center. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
