| Sumario: | [EN] 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, & mldr;) and valorizing the e-waste in its own. Here, it is shown that a metallic contact (approximate to 1 mg) of a computer<acute accent>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<acute accent>s recycling bin. These results open the way to directly use e-waste in catalysis for organic synthesis. |
