Random Access Memory (RAM) Contacts Waste Catalyzes Organic Reactions

Global Challenges, EarlyView.
Wasted RAM contacts catalyze different organic reactions in good to excellent yields, with turnover numbers >0.5 million in some cases. The RAM contacts are used without any previous treatment and are recovered and reused. Kilograms of organic products could be produced with the RAM contacts of just five discarded laptops. These results open the way to
