Post navigation The Pac-12 and Big Ten conferences have agreed to an eight-team partnership for the 2023 football season. This plan will see the two conferences competing head-to-head in interconference matchups between Oregon and Washington. As part of the agreement, the partnership is expected to produce a pair of high-profile matchups between the Pac-12 and Big Ten every year. Penn researchers developed a useful new procedure for synthesizing and producing cyclopropanes. It involves combining a compound called a nitrile imine with an alkene in the presence of a particular type of copper catalyst. By using this method, intermediate organic molecules can be created more quickly and more economically.
