Synthesis of an Anthracene-Based Macrocyclic Diphosphine Ligand

Autor: Wesley J. Transue, Martin-Louis Y. Riu, Ioana Knopf, Christopher C. Cummins

Publikováno v: Organometallics. 39:4187-4190

The synthesis and coordination chemistry of cis-macrocyclic diphosphine (PhPA)2 (A = C14H10 or anthracene), which features rigid, sterically encumbering groups in its macrocyclic backbone, is repor...

Uptake of one and two molecules of CO2 by the molybdate dianion: a soluble, molecular oxide model system for carbon dioxide fixation

Autor: Christopher C. Cummins, Takashi Ono, Manuel Temprado, Ioana Knopf, Daniel Tofan

Publikováno v: RSC

Tetrahedral [MoO4][superscript 2−] readily binds CO[subscript 2] at room temperature to produce a robust monocarbonate complex, [MoO[subscript 3](κ[superscript 2]-CO[subscript 3])][superscript 2−], that does not release CO[subscript 2] even at m

Revisiting CO2 Reduction with NaBH4 under Aprotic Conditions: Synthesis and Characterization of Sodium Triformatoborohydride

Autor: Ioana Knopf, Christopher C. Cummins

Publikováno v: Organometallics. 34:1601-1603

The reduction of CO2 to formate using sodium borohydride was originally investigated in the 1950s. Despite this clue from the chemical literature, many recent publications describe catalytic CO2 hydroboration methods leading to formate or methoxide w
