Copolymerization of olefin with carbon monoxide has received considerable interest from both academia and industry, and the introduction of polar carbonyl group renders the resultant polyketones with excellent mechanical strength, crystallinity, photodegr
Ligand-free copper-catalyzed denitrogenative arylation of phosphorylamides with arylhydrazines

, p. 947 - 957 (2020/02/27)
A straightforward arylation of phosphorylamides with arylhydrazines hydrochloride was herein demonstrated. The protocol proceeded in the presence of a catalytic loading of Cu(OAc)2 as the catalyst, DTBP as the external oxidant and Cs2CO3 as the base, but without any ligands. And a series of N-aryl phosphorylamides were successfully obtained in high efficiency (up to 93% yields) with good substituents compatibility (up to 30 examples). Free radical mechanism was proposed for the facile methodology based on the results of control reactions and literature explorations.

The ability to carry out transition-metal-catalyzed copolymerizations of olefins with polar monomers is a great challenge in the field of olefin polymerization. Palladium has been the dominant player in this field, while its low-cost nickel counterpart has only achieved very limited success. We report the synthesis and evaluation of a highly versatile platform based on diphosphazane monoxide ligands. Both palladium and nickel catalysts bearing these ligands mediate the copolymerization of ethylene with a number of fundamental polar monomers.
