A switchable access to ethenylphosphorylamides and chloroethenylphosphorylamides from phosphorylamides and alkenes has been disclosed herein. With the assistance of Pd(OAc)2, a catalytic loading of CuCl2 or CuBr (20 mol‐%) led to the occurrence of dehydrogenative cross coupling reactions with high efficiency and broad substrate scope, while 1.0 equivalent of CuCl2 rendered the dehydrogenative amidochlorination reactions to take place with high stereoselectivity.

Abstract A practical preparation of nitroarylamines from protected arylamines was herein disclosed. In this system, sodium nitrite acted as a nitration reagent in the presence of sodium persulfate without any transition-metal catalysts. This efficient site-selective protocol took place at room temperature for a short time through a free radical pathway. Graphical abstract A site-selective preparation of nitroarylamines was herein disclosed from protected arylamines and sodium nitrite in the presence of Na 2 S 2 O 8 without any transition-metal-catalysts. The mild protocol took place at room temperature for a short time through a free radical mechanism with broad substrate scope and high efficiency. Image 1 [ABSTRACT FROM AUTHOR]
