V. V. Dunina O. N. Gorunova Yu. K. Grishin L. G. Kuz’mina A. V. Churakov A. V. Kuchin J. A. K. Howard 《Russian Chemical Bulletin》2005,54(9):2073-2082
The reaction of benzylaminate CN-palladacycle with chlorine dioxide was found to produce the 3-chlorine-substituted analog through the formal insertion of
chlorine into the Pd-C bond followed by repeated ortho-palladation of the modified ligand. The structure of the resulting dimeric complex was confirmed by X-ray diffraction study
of its triphenylphosphine derivative. A comparison of the 1H NMR spectra of the phosphine adducts of the starting and chlorinated complexes shows high conformational stability of the
new palladacycle. Advantages of the new route to conformational stabilization of labile palladacycles are discussed.

A convenient one‐pot synthetic protocol towards THF and DME solvates of lanthanum and other early lanthanide tribromides was developed using the water‐catalyzed reaction of lanthanide(III) oxides with highly reactive Me3SiBr in situ formed from commercially available disilane Si2Me6 and Br2. This practical route allows to obtain the target lanthanum tribromide solvates [LaBr3(thf)4] ( 1a ) and [LaBr3(dme)2]2 ( 1b ) as well as analogous early lanthanide molecular tribromide solvates [NdBr3(thf)4] ( 2a ), [NdBr3(dme)2] ( 2b ), [SmBr3(thf)2] ( 3a ), and [SmBr3(dme)2] ( 3b ) difficult to prepare by other solution‐based procedures. The molecular structure of 1b· 2CH2Cl2 was determined by an XRD study. 相似文献

Two compounds of a novel‐type azagermatrane, N(CH2CH2NC6F5)3Ge‐Hal: HalCl ( 1 ), Br ( 2 ), were prepared via a metathetical reaction of trilithium salt of tetramine, N[CH2CH2N(Li)C6F5]3, with corresponding GeHal4. A single crystal structure of 1 was determined by the X‐ray diffraction study: The compound shows the strongest transannular Nax → Ge interaction (2.148(7) Å) among other studied azagermatranes. © 2008 Wiley Periodicals, Inc.

4-methoxyphenyl-4′-n-nonyloxybenzoate have been investigated by single crystal X-ray structural analysis. Crystal packing of the compounds does not represent a precursor of the mesophse although the typical for liquid crystal compounds separation of crystal packing on aromatic and aliphatic areas is observed here. Possible reason for monotropic properties are discussed. 相似文献
