摘要

直接利用来自电子废物(电子废物)的金属进行催化是一个几乎没有探索的概念,然而,对于可以从电子废物金属块原位形成催化活性物质的反应来说,应该是可行的。这种方法避免了对特定金属的任何捕获或隔离,从而节省了额外的处理(提取、中和、分离、洗涤等),并使电子废物本身增值。本文表明,计算机随机存取存储器(RAM)的金属接触(≈1 mg)可以催化多种高产量的有机反应。例如,在室温下,一个RAM接触催化酰基氯、丙炔醇和水之间的一锅酯化-水化反应,收率为93-99%,周转率为每小时50万次。这样,每年仅用研究所回收箱中丢弃的RAM触点就可以制备50公斤有机产品。这些结果为直接利用电子垃圾催化有机合成开辟了道路。

Random Access Memory (RAM) Contacts Waste Catalyzes Organic Reactions

Random Access Memory (RAM) Contacts Waste Catalyzes Organic Reactions

The direct utilization of metals from electronic waste (e-waste) in catalysis is a barely explored concept that, however, should be feasible for reactions where the catalytically active species can be formed in situ from the e-waste metal pieces. This approach circumvents any capture or isolation of particular metals, thus saving additional treatments (extractions, neutralization, separations, washings, …) and valorizing the e-waste in its own. Here, it is shown that a metallic contact (≈1 mg) of a computer´s random-access memory (RAM) catalyzes a variety of organic reactions in high yields. For instance, one RAM contact catalyzes the one-pot esterification-hydration reaction between acyl chlorides, propargyl alcohols, and water, at room temperature in 93–99% yields with turnover frequencies >0.5 million per hour. In this way, >50 kg of organic products could be prepared with just the RAM contacts discarded per year in the Institute´s recycling bin. These results open the way to directly use e-waste in catalysis for organic synthesis.
