Towards the end of the transition series, effective bond orders drop, resulting in formal nitrido complexes with significant subvalent nitridyl (MN) or limiting metallonitrene (M–N) contributions to the electronic structure, thus increasing N-radical character. The significantly weakened M–N ...
Significantly, [κ4-B(mimBut)3]Fe(CO)2 exhibits novel reactivity towards a variety of reagents that results in eradication of the Fe→B bond via a formal 1,2-addition process and the formation of B-functionalized tris(mercaptoimidazolyl)borate derivatives, [XTmBut]FeY. 展开 DOI: 10.1021/...

Thus, a series of 1,3-bisfunctionalized indol-2-yl rare-earth metal complexes bearing electrophilic and nucleophilic carbon centres were synthesized, and their reactivities towards pyridine derivatives were extensively studied with findings of unusual reactivity patterns. Herein, we report these results....
The impact of two other characteristics of these metal carbenoids, namely their singlet or triplet state and their electrophilic or nucleophilic reactivity towards π-bonded substrates, is also assessed in exploring their possible modes of ... JJ Eisch - 《Journal of Organometallic Chemistry》 被引...
