C3-Chiral Tripodal Amido Complexes

Chemistry - A European Journal, 2001
A comprehensive study into the coordination chemistry of two C3-chiral tripodal amido ligands has been carried out. The amido ligands contain a trisilylmethane backbone and chiral peripheral substituents. The amine precursors. HC(SiMe2NH[(S)-1-phenylethyl]]3 (1) and HC[SiMe2NH[(R)-1-indanyl]]3 (2) were found to be in equilibrium in solution with the ...

Amido Phosphine Complexes of Zinc

Inorganic Chemistry, 2003
The first examples of amido phosphine complexes of zinc have been prepared. Addition of N-(2-diphenylphosphinophenyl)-2,6-diisopropylaniline (H[NP]) to ZnMe(2) or ZnEt(2) in diethyl ether at -35 degrees C generated the monomeric, three-coordinate [NP]ZnR (R = Me, Et), while the metathesis reaction of ZnCl(2) with [NP]Li(THF)(2) in diethyl ether at -35 ...

Multiple States of Dimeric Aggregates Formed by (Amido–ethynyl)helicene Bidomain Compound and (Amido–ethynyl–amido)helicene Tridomain Compound

Chemistry – A European Journal, 2012
AbstractAn (amido–ethynyl)helicene bidomain compound and an (amido–ethynyl–amido)helicene tridomain compound were synthesized. The multidomain compounds were designed on the basis of previous findings that amido and ethynyl oligomers form dimeric aggregates with properties orthogonal to each other. Four aggregate states of multidomain compounds, namely,

Lithium Dimethyl(amido)zinc Complexes:  Contrasting Zincate (Amido = TMP) and Inverse Zincate (Amido = HMDS) Structures on Addition of TMEDA

Organometallics, 2006
Introducing TMEDA to the lithium dimethyl(amido)zincates “LiZn(NR2)Me2” leads to a discrete ion-contacted zincate with TMEDA bound to lithium in the case of NR2 = TMP but to a novel “inverse zincate” with TMEDA bound to zinc in the case of NR2 = HMDS, where unexpectedly Me2Zn(TMEDA) functions as a η1,μ ligand to dimeric (LiHMDS)2 molecules to afford a ...

Lanthanon(III) Amido Complexes

Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1981
Abstract Ln(NHCOR)3 (I) and Ln(SCNHCH3)3 (II) are prepared and characterized by elemental analysis, electronic and infrared spectra (Ln = La, Pr, Nd, Sm; R = CH3, C6H5, C5H4N). The bonding of matal to amide is through nitrogen in I while it is through sulphur in II.
