Electrocatalytic reduction of CO2to CO and HCO2?with Zn(ii) complexes displaying cooperative ligand reduction

Air-stable zinc(ii) pyridyl phosphine complexes, [Zn(κ2-2,6-{Ph2PNMe}2(NC5H3))Br2] (1) and [Zn(κ2-2-{Ph2PNMe}(NC5H3))Br2] (2) are repo

Employing a neutral “PN3P” pincer to access mer-Re(I) tricarbonyl complexes: Autoionization of a halo ligand and the role of an N-R (R = H, Me) substituent

A series of monovalent Re complexes, mer-[Re{κ3-2,6-(Ph2PNH)2NC5H3}(CO)3]+, cis-[Re{κ3-2,6-(Ph2PNMe)2NC5H3}(CO)2Cl], and mer-[Re{κ3-2,6-(Ph2PNMe)2NC5H3}(CO)3]+ supported by neutral “PN3P” ligands have been synthesized by addition of pincer ligand to Re(CO)5X (X = Cl, Br). The products were characterized by multinuclear NMR and single crystal X-ray diffraction studies and showed a dependence on the identity of the halo ligand in starting material and on the substitution pattern of the pincer ligand. The formation of the mer-Re(CO)3 core geometry and the autoionization of halide ligand in the majority of these species is in marked contrast to the bulk of the literature on the substitution chemistry of Re(I) carbonyl halides.

A complete series of halocarbonyl molybdenum PNP pincer complexes - Unexpected differences between NH and NMe spacers Dedicated to Prof. Dr. Maria José Calhorda on the occasion of her 65th birthday.

In the present study a complete series of seven-coordinate neutral halocarbonyl Mo(II) complexes of the type [Mo(PNPMe-Ph)(CO) 2X2] (X = I, Br, Cl, F), featuring the new PNP pincer ligand N,N′-bis(diphenylphosphino)-N,N′-methyl-2,6-diaminopyridine (PNPMe-Ph), were prepared and fully characterized. The synthesis of these complexes was accomplished by different methodologies depending on the halide ligands. For X = I and Br, [Mo(PNPMe-Ph)(CO)2I 2] and [Mo(PNPMe-Ph)(CO)2Br2] were obtained by reacting [Mo(PNPMe-Ph)(CO)3] with stoichiometric amounts of I2 and Br2, respectively. Alternatively, these complexes were obtained upon treatment of [MoX 2(CO)3(CH3CN)2] (X = I, Br) with 1 equiv. of PNPMe-Ph. On the other hand, in the case of X = Cl, [Mo(PNPMe-Ph)(CO)2Cl2] was afforded by the reaction of [Mo(CO)4(μ-Cl)Cl]2 with 1 equiv. of PNPMe-Ph. The equivalent procedure also worked for X = Br. Finally, addition of 1 equiv. of 1-fluoro-2,4,6-trimethylpyridinium tetrafluoroborate to [Mo(PNPMe-Ph)(CO)3] yielded the analogous fluorine complex [Mo(PNPMe-Ph)(CO)2F2]. The modification of the ligand scaffold by introducing a Me group instead of H changed the properties of the PNP-Ph ligand significantly. While in the present case exclusively neutral seven-coordinate complexes of the type [Mo(PNPMe-Ph)(CO) 2X2] were obtained, with the parent PNP-Ph ligand, i.e., featuring NH spacers, cationic seven-coordinate complexes of the type [Mo(PNP-Ph)(CO)3X]X were afforded. DFT calculations indicated that the reactions are under thermodynamic control. The structures of representative complexes were determined by X-ray single crystal analyses.
