Applied Organometallic Chemistry

β-diketiminato ytterbium aryloxides were proven to be efficient precatalysts for addition of amines to carbodiimides giving guanidines with a wide range of substituents.

N-(ferrocenylmethyl amino acid) fluorinated benzene-carboxamide derivatives have been synthesised and biologically evaluated on the estrogen positive MCF-7 breast cancer cell line. N-(ferrocenylmethyl-L-alanine)-3,4,5-trifluorobenzene-carboxamide 5h was the most active compound with an IC₅₀ value of 2.84 μM.

Bis(phenoxy-imine) zirconium complexes bearing bulky o-bis(aryl)methyl- substituted aryl groups on the aniline moiety have been synthesized, characterized and tested as catalyst precursors for ethylene polymerization. The introduction of a excessively bulky o-bis(aryl)methyl substituents adjacent to the the imine-N produces low molecular weights aluminium terminated polyethylenes (Al-PEs) (M_v 1.6–10.1 × 10³) due to the enhanced rate of chain transfer to alkylaluminum groups during the polymerization.

An optimized terpolymer organosilicate resist prepared with p-chloromethylphenyl trimethoxysilane, norbornene ethyltrimethoxysilane, and tetraethoxysilane exhibits an excellent stability and allows the fabrication of 20-nm patterns with excellent line-edge roughness, with one quarter of the required dose for conventional HSQ resist.

A systematic study showed, the encapsulated Pd(OAc)₂/ethylenediamine complex into the SBA-15 as an organic–inorganic hybrid nanoreactor (Pd(OAc)₂@SBA-15/PrEn) exhibit higher activity and selectivity toward Suzuki cross-coupling reaction in aerobic condition and mixture of water solvent.
