The Aldehyde-Water Shift (AWS) reaction uses H2O as a benign oxidant to convert aldehydes to carboxylic acids, producing H2, a valuable reagent and fuel, as its sole byproduct. (Hexamethylbenzene)RuII complexes are demonstrated to have higher activit

A new pincer ligand framework based on the commonly used “POCOP” (POCOP = κ3-C6H3-1,3-(OPR2)2, R = tBu, iPr) motif is reported, in which two POCOP units are tethered using an anthracene linker to s...

Reduced steric demand of the Me4PCP pincer ligand (PCP = κ3-C6H4-1,3-[CH2PR2]2, R = Me), allows for a more open metal center. This is evident through structure and reactivity comparisons between (Me4PCP)Ir derivatives and other (R4PCP)Ir complexes (

Reactions of (X)(tBu)4(POCOP)Ir(CO) [(X)(tBu)4(POCOP) = κ3-C6H2-2,6-(OP(tBu)2)2-4-X where X = H, Me, COOMe, OMe, NMe2] complexes with iodine proceed to form Ir(III) iodide carbonyl complexes. When X = H, Me, or COOMe, cis-diiodide carbonyl complexes

Addition of high pressures of H2 to five-coordinate [(tBu)4(POCOP)Ir(CO)(H)]OTf [(tBu)4(POCOP) = κ3-C6H3-2,6-(OP(tBu)2)2] complexes results in observation of two new iridium–dihydrogen complexes. If the aryl moiety of the POCOP ligand is substitut

A pair of POCOP-supported mono- and dicarbonyl complexes of Co have been prepared and crystallographically characterized. The reactivity of (tBuPOCOP)Co(CO) with H2, acids, and carbon monoxide has been compared to that of the previously reported Rh a

We present a new synthetic method for the bis(dimethyl)phosphines Me4PCP (C6H4-2,6-(CH2P(CH3)2)2) and DMPE ((CH3)2PCH2CH2P(CH3)2) that starts from an aminophosphine, Et2NPMe2. Two equivalents of Et2NPMe2 react with the corresponding bis(alkyl bromide

A family of (para-cymene)RuII complexes are shown to be competent precatalysts for the oxidation of aldehydes to carboxylic acids using water as the oxidant. This reaction, known as the “aldehyde–water shift” (AWS), has been previously demonstr

Pincer ligand metalation is presumed to proceed via initial coordination to the phosphorus atoms followed by C–H oxidative addition. Few isolated intermediates in this process are known. A rhodium phosphinite complex has been isolated and structura
