在科研中问出更多的What if---读William Evans的“A Rare-Earth Metal Retrospective to Stimulate All Fields”有感 著名金属有机化学家William Evans在JACS最近写了一篇非常有意思的perspective,读完后让我深有感触。 https://pubs.acs.org/doi/10.1021/jacs.1c08288pubs.acs.org/doi/10.1021/jacs.1c08288...
Metal–metal bonding in heterometallic complexes is of fundamental interest due to its implications in both bonding theory and new reactivities. In this review, structurally authenticated molecular compounds with direct bonds between rare earth metals and transition or main group metals are summarized. No...
