摘要：

(Chemical Equation Presented) A pinch of platinum... Platinum(II)-catalyzed cyclization of 1,2,4-trienes proceeds under mild conditions to give well-defined, highly substituted cyclopentadienes in good yield. The reaction was confirmed to proceed through α,β-unsaturated platinum-carbene complex intermediates (see scheme). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
