β-Hydrogen Elimination Reactions of Nickel and Palladium Methoxides Stabilised by PCP Pincer Ligands
(John Wiley & Sons, 2015)
Nickel and palladium methoxides [((iPr)PCP)M-OMe], which contain the (iPr)PCP pincer ligand, decompose upon heating to give products of different kinds. The palladium derivative cleanly gives the dimeric Pd(0) complex ...

Hydrogenation of imines catalysed by ruthenium(ii) complexes based on lutidine-derived CNC pincer ligands
(Royal Society of Chemistry (Great Britain), 2013)
The preparation of new Ru(ii) complexes incorporating fac-coordinated lutidine-derived CNC ligands is reported. These derivatives are selectively deprotonated by tBuOK at one of the methylene arms of the pincer, leading ...

Sequential reduction and alkyl exchange reactions of bis(imino)pyridine dialkyliron(II) with trimethylaluminum
(American Chemical Society, 2014)
The sequence of reactions ensuing when the 2,6-bis(imino)pyridine Fe(II) dialkyl complexes [Fe(CH2SiMe3)2(BIP)] react with trimethylaluminum is described in detail. The first step is the reduction of the dialkyl to the ...
