Abstract:	摘要： The bulky bis(carbene)borate ligand Ph2B(tBuIm)2 – stabilizes low-coordinate and low-valent iron complexes. The four-coordinate iron(II) complex Ph2B(tBuIm)2FeCl(THF) is a precursor to the low-spin iron(I) complex Ph2B(tBuIm)2Fe(CO)3. Despite a reversible reduction wave in the cyclic voltammogram, access to the iron(0) complex [Ph2B(tBuIm)2Fe(CO)3]− requires reduction under a CO atmosphere. Without excess CO, KC8 reduction leads to formation of the dimer K2[Ph2B(tBuIm)2Fe(CO)2] along with loss of CO. Each iron center in this complex adopts a distorted-square-planar geometry. Spectroscopic analysis of these carbonyl complexes reveals the very high strength of the bis(carbene)borate ligand. 其他題名： Organometallics 出版者： American Chemical Society 出版日期： 2016-09-12 出處： Organometallics, 2016-09, Vol.35 (17), p.3069-3073 資源來源： American Chemical Society Journals 版權： Copyright © 2016 American Chemical Society 識別號： ISSN: 0276-7333 識別號： EISSN: 1520-6041 識別號： DOI: 10.1021/acs.organomet.6b00599
