摘要：
(Chemical Equation Presented) Three's a charm, but four's not half bad either: A simple cobalt-diphosphine complex facilitates the synthesis of cyclobutene derivatives through the chemoselective transformation of strained five-membered unsaturated rings with internal alkynes (see scheme). This atom-efficient, intermolecular reaction generates polycyclic products in excellent yields and with excellent exo selectivity. dppp=1,3- bis(diphenylphosphanyl)propane. © 2008 Wiley-VCH Verlag GmbH & Co.
