Physically entrapped dichlorobis(triphenylphosphine)palladium(II) within a silica sol–gel matrix is an efficient catalyst for cross-coupling of aryl iodides, bromides and triflates with intramolecularly stabilized dimethyl- and diethylindium alkyla

While the intramolecularly stabilized aluminum complex [(CH3)2AlOCH2CH2N(CH3)2]2 (2a) reacts readily with 4-bromophenol to give methane and [(4-BrC6H4O)2AlOCH2CH2N(CH3)2]2 (7), the demethylation of the analogous indium complex [(CH3)2InOCH2CH2N(CH3)2

Several phenyl and naphthyl triflates undergo catalytic cross-methylation with the monomeric and dimeric dimethyl-aluminum, -gallium and -indium complexes 1a , 1b , 1c , 3a , 3b and 3c in the presence of either PdCl 2 (PPh 3 ) 2 , Pd(PPh 3 ) 4 or Pd(

Although the intramolecularly stabilized [(3-dimethylamino)propyl]dimethylaluminum (1a) fails to undergo palladium-catalyzed cross-coupling with bromopyridines and with bromofuran derivatives, the analogous gallium and indium reagent 1b and 1c smooth

Gold nanoparticles, AuNPs, capped with mercaptocarboxylic acids followed by silver precipitation develop latent fingermarks on paper as high quality "negative" impressions. This effect stems from hydrogen bonding between the carboxylic group and the
