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 ...

Synthesis and Reactivity Studies of Amido-Substituted Germanium(I)/Tin(I) Dimers and Clusters.
Chemistry, 2018Three amide ligands of varying steric bulk and electronic properties were utilized to prepare a series of amido-germanium(II)/tin(II) halide compounds, (LEX)n , (L= -N{B(DipNCH)2 }(SiMe3 ), TBo L; -N{B(DipNCH)2 }(SiPh3 ), PhBo L; -N(Dip)(tBu), DBu L; Dip=

This report describes the synthesis and characterization of a series of octaethylporphyrin derivatives in which the porphyrin pi-network is connected to phenyl, 3-fluoranthenyl, or 1-pyrenyl aromatic systems through a meso amino or amido nitrogen. Metal-free bases and zinc(II) and iron(III) complexes have been obtained.

Lanthanon(III) Amido Complexes [PDF]
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.

A BF3-etherate-promoted cascade reaction of nitriles with 2-alkynylanilines is described. This method achieves the formation of two new C-N bonds through a reaction sequence of diazotization with t-BuONO, nucleophilic addition of the alkyne to the BF3 ...
