"The strong performance in industrial metals isn't being mirrored by precious metals. A slump in investment flows to the yellow metal, catalyzed by the election uncertainty which cascaded to deflationary forces from potential Covid-19 lockdowns and a reversal in safe-haven flows from the vaccine...
摘要: A metal- and base-free synthesis of functionalized α,α-difluoroimines is presented. The reaction features mild conditions, high E/Z control and broad functional group tolerance. The utility of the products was demonstrated through valuable synthetic transformations....
