A New Binding Motif of Sterically Demanding Thiolates on a Gold Cluster
摘要:
A gold cluster, Au-41(S-Eind)(12), was synthesized by ligating the bulky arenethiol 1,1,3,3,5,5,7,7-octaethyl-s-hydrindacene-4-thiol (Eind-SH) to preformed Au clusters. Extended X-ray absorption fine structure, Xray photoelectron spectroscopy, and the fragmentation pattern in the mass spectrometry analysis indicated that formation of gold thiolate oligomers at the interface was suppressed, in sharp contrast to conventional thiolate-protected Au clusters.
Monomeric diaryliron(II) complexes, Fe(Rind)2, have been obtained by introducing fused-ring bulky “Rind” groups. For Fe(Eind)2, a significant orbital contribution of the Fe(II) ion due to the linea...

Synthesis and Structures of a Series of Bulky “Rind-Br” Based on a Rigid Fused-Ring<i>s</i>-Hydrindacene Skeleton
A series of octa-R-substituted bromo-s-hydrindacenes, “Rind-Br,” have been synthesized by a sequence of the Lewis acid catalyzed intramolecular Friedel–Crafts reaction, bromination and vice versa. Their structural features and physical properties depend on the eight R-substituents at the four benzylic positions on the s-hydrindacenyl skeleton. The molecular structures of the Rind-Br have been confirmed by X-ray crystallography, indicating the unique structural diversities of the bulky Rind groups.
