Ni-catalyzed asymmetric C-P cross-coupling reaction via Ni(I)/Ni(III) two-electron pathway [PDF]
, 2023 Nickel demonstrates excellent performance in C-C or C-X cross-coupling reactions involving a SET process. However, the Ni(I)/Ni(III) two-electron pathway, which does not require light irradiation, is still rare, particularly in the asym-metric version ...

Korean Journal of Mathematics, 2016 Summary: Let \(R\) be a ring. It is well-known that \(R\) is \(NI\) if and only if \(\sum_{i=0}^nRa_iR\) is a nil ideal of \(R\) whenever a polynomial \(\sum_{i=0}^na_ix^i\) is nilpotent, where \(x\) is an indeterminate over \(R\). We consider a condition which is similar to the preceding one: \( \sum_{i=0}^nRa_iR\) contains a nonzero nil ideal of \(R\)
