Copper in a cage: We describe an approach to cage metallasilsesquioxanes by self-assembly with 1,2-bis(diphenylphosphino)ethane as a key reactant. Initial tests for the application of the synthesized complexes as catalysts reveal their very high activity in the homogeneous oxidation of alkanes and alcohols to produce alkyl hydroperoxides, ketones, and amides.

四环和无环笼式铜（II）苯基倍半硅氧烷的离子配合物：合成和高活性的氧化催化。

笼子中的铜：我们描述了一种通过以1,2-双（二苯基膦基）乙烷为主要反应物进行自组装来制备笼形金属硅倍半氧烷的方法。最初将合成的络合物用作催化剂的测试表明，它们在烷烃和醇的均相氧化过程中具有很高的活性，可生产烷基氢过氧化物，酮和酰胺。
