Metallacycloprop-1-enes can be constructed from coordinated alkynes. In this work, we report a convenient synthesis of fused osmacyclopropene complexes 1 and 3 from OsCl(PPh) and alkynylphenols. Paramagnetic alkyne-coordinated phenolate complexes 2 were obtained as the key intermediates for the formation of osmacyclopropenes, demonstrating selective CC activation under different conditions.
金属环丙烯可以由配位炔烃构建而成。在本研究中，我们报道了一种由OsCl(PPh)和炔基酚简便合成稠合锇环丙烯配合物1和3的方法。顺磁性的炔烃配位酚盐配合物2作为形成锇环丙烯的关键中间体得以获得，这表明在不同条件下存在选择性的CC活化。
