    Bond order resolved 3d 5/2 and valence band chemical shifts of Ag surfaces and nanoclusters by Sun, Changqing, Qin, Wei, Wang, Yan, Huang, Yongli, Zhou, Zhaofeng, Yang, Chao

    Published 2013
    “…It is clarified that the globally positive energy shifts originate from the undercoordination-induced Goldschmidt–Pauling bond contraction and the associated local quantum entrapment and the heterocoordination-induced bond nature alteration at the particle–substrate interfaces. …”

    Catalytic asymmetric diarylphosphine addition to α-diazoesters for the synthesis of P-stereogenic phosphinates via P*-N bond formation by Balázs, László B., Huang, Yinhua, Khalikuzzaman, Jasmina B., Li, Yongxin, Pullarkat, Sumod A., Leung, Pak-Hing

    Published 2022
    “…The asymmetric catalytic P-H addition of racemic secondary phosphines to electrophilic α-diazoesters via P*-N bond formation is disclosed for the first time. Interaction between the diazoester and the palladium catalyst resulted in the unusually enhanced electrophilic ability of the terminal nitrogen in the diazo functionality, as opposed to the commonly expected formation of a metal carbene by nitrogen elimination. …”

    Facile access to chiral ketones through metal-free oxidative C-C bond cleavage of aldehydes by O2 by Tiwari, Bhoopendra, Zhang, Junming, Chi, Robin Yonggui

    Published 2012
    “…Giving the metal the boot: The title reaction provides facile access to functionalized chiral ketones from chiral α,α′-disubstituted aldehydes in the presence of molecular oxygen (see scheme). The CC bond-cleavage approach offers an alternative or better method relative to the typical bond-forming strategies used in synthesizing chiral ketones.…”
