Cross‐Carboxylation of Methanol and Other Alcohols With CO2 Into Asymmetric Alkyl Methyl Carbonates Over a CeO2 Catalyst

open access: yesChemistry – A European Journal, EarlyView.
One‐pot synthesis of asymmetric organic carbonates from CO2, methanol, and other alcohols was demonstrated in the presence of CeO2 catalyst and 2‐cyanopyridine dehydrant. This reaction proceeded through two reaction pathways—direct route via cross‐carboxylation and indirect route via production of DMC and subsequent transesterification.

Isodesmic Supramolecular Assembly of Phenylethynylene Bis‐Urea Macrocycles

open access: yesChemistry – A European Journal, EarlyView.
A soluble phenylethynylene bis‐urea macrocycle assembles in polar media via an isodesmic hydrogen bonded mechanism. Spectroscopic and morphological studies reveal nanoscale aggregates with short chain length, while guest additives modulate enthalpy and polymerization, demonstrating tunable supramolecular assembly.

Azidophosphonamido Rhodium(I) and Iridium(I) Complexes: Synthesis, Properties, and Linkage Isomerism

open access: yesChemistry – A European Journal, EarlyView.
A family of azidophosphonamido ligands and their corresponding rhodium(I) and iridium(I) complexes were synthesized. The rich reaction chemistry of these species revealed unusual linkage isomerization processes and bonding motifs. M = Rh, Ir; Mes = 2,4,6‐Me3C6H2. ABSTRACT A series of azidophosphonamido rhodium(I) and iridium(I) complexes ([iPr2P(N3R)NR]

Synthesis of the Phospha‐Wittig Reagent Me3P = P(C2F5) and Generation of a Phospanyl‐Wittig Derivative Me3P = C(CF3)P(C2F5)F

open access: yesChemistry – A European Journal, EarlyView.
The first example of a simple alkylated phosphinidene‐adduct (“phospha‐Wittig”) is reported. The synthesis of Me3PPC2F5 was enabled through reaction of the cyclotetraphosphane (PC2F5)4 with PMe3. The phosphanyl‐functionalized Wittig reagent Me3PC(CF3)P(C2F5)F was prepared by treating the diphosphane P2(C2F5)4 with PMe3.
