DIVE&CLEAN - Intervention Possible
The DIVE&CLEAN project is an educational and innovative initiative aimed at addressing a significant environmental challenge: marine pollution. With oceans covering over 70% of the Earth’s surface and providing a home to 50–80% of life on the planet, their health is critical. However, marine ecosystems are under threat due to plastic pollution, which impacts wildlife, coastal communities, and global biodiversity. This project centers around the idea of introducing underwater trash bins, especially in areas frequented by recreational divers. While most divers explore the seas without specific tools to collect trash, they could contribute significantly with the right infrastructure. The vision of DIVE&CLEAN is to inspire behavioral change, encourage collaboration, and promote actionable solutions to reduce ocean pollution. Using interactive robotics and storytelling, the project tells the story of divers rescuing animals entangled in plastic and collecting trash from the ocean floor using underwater bins. Through creative performances, it seeks to educate and motivate individuals, resorts, and authorities to adopt sustainable practices.
一價銠金屬催化肉桂胺衍生物進行不對稱氫芳基化反應
Rhodium(I)-Catalyzed Asymmetric Hydroarylation of Cinnamylamine Derivatives
一價銠金屬催化反應已經被廣泛應用於有機化學合成領域中。而本研究以具保護基之肉桂胺衍生物1與四芳基硼鈉試劑2a作為起始物進行銠金屬不對稱氫芳基化催化反應，得到具有保護基的掌性2,3-雙芳基丙胺衍生物3，並探討此反應的掌性雙烯配基對於反應的影響。本研究已完成使用Ts（對甲苯磺醯基）保護基之肉桂胺衍生物1a作為起始物進行反應，並改變與銠金屬錯合的配基，發現當配基使用2,5號位為芳基取代之配基L（掌性雙環[2,2,1]雙烯配基）時，反應有較好的位置選擇性，其中最佳的是芳基取代為苯基之配基L1，其位置選擇性比例為1:0:0.09。目前將進行改變起始物1之氮上的保護基，以L1作為配基進行反應，並與1a比較，優化反應性及產率。
