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 ...

A Diels–Alder Reaction Triggered by a [4 + 3] Metallacycloaddition
(American Chemical Society, 2015)
The TpMe2Ir(III) complex 1-OH2 (TpMe2 = hydrotris(3,5-dimethylpyrazolyl)borate), which contains a labile molecule of water and an iridium-bonded alkenyl moiety (−C(R)═C(R)–(R=CO2Me)) as part of a benzo-annulated five-membered ...

Synthesis and Reactivity of Nickel an Palladium Fluoride Complexes with PCP Pincer Ligands. A NMR-Based Assessment of Electron-Donating Properties of Fluoride and Other Monoanionic Ligands
(American Chemical Society, 2012)
A series of complexes of the type [(iPrPCP)M-L] (M = Ni, Pd), containing the 2,6-bis(diisopropylphosphinomethyl)phenyl (iPrPCP) pincer ligand and simple monoanionic ligands L (F, Cl, Br, H, Me, Ph, NO3, and OTf), have been ...

Novel bis (1,3,2-diazaphospholidine) ligands for asymmetric catalysis
(American Chemical Society, 2013)
A family of modularly designed chiral bis(1,3,2-diazaphospholidines) with N-aryl substituents (NP-PN) is reported. These compounds have been prepared in two steps from readily available (R,R)-1,2-diaminocyclohexane and ...

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 ...

Protonolysis of Fe-C bonds of a diiminopyridineiron(II) dialkyl complex by acids of different strengths: Influence of monoanionic ligands on the spectroscopic properties of diiminopyiridine-FeY2 complexes
(Elsevier, 2014)
The reaction of the dialkyliron complex [Fe(CH2SiMe 3)2(MesBIP)] (MesBIP = 2,6-bis((N-mesityl)acetimidoyl)pyridine) with protic acids (HY) of different strengths (Y = C6F5O, CF3CO2, Cl, CF3SO3) invariably leads to the ...

Asymmetric organocatalytic Strecker-type reactions of aliphatic N,N-dialkylhydrazones
(Royal Society of Chemistry (Great Britain), 2013)
The enantioselective organocatalytic Strecker-type reaction of aliphatic N,N-dialkylhydrazones is presented. Using trimethylsilyl cyanide (TMSCN) as the cyanide source, the reaction can be efficiently catalyzed by a ...

Synthesis and characterization of enantiopure chiral NH2/SO palladium complexes
(Royal Society of Chemistry, 2023)
A series of enantiopure chiral NH2/SO palladium complexes have been synthesised with high yields by treating the corresponding tert-butylsulfinamide/sulfoxide derivatives with Pd(CH3CN)2Cl2. The enantiopure chiral ligands ...

Migratory insertion reactions of nickel and palladium σ-alkyl complexes with a phosphinito-imine ligand†‡
(Royal Society of Chemistry (Great Britain), 2012)
Ligand exchange reactions have been used for the synthesis of metallacyclic complexes of Ni and Pd of the type [M[upper bond 1 start](CH2CMe2-o-C6[upper bond 1 end]H4)(P–N)], where P–N is the phosphinito-imine ligand ...
