A novel trithiadiazapentalene derivative with exocyclic C–N double bonds

Abstract

The structure of 3,4-ethano-2,3,4,5-tetrahydro-2,5-bisphenylimino-l,6,6a,Srv-trithia-3,4-diazapentalene (I) has been confirmed by X-ray crystallography.THE structure (I), assigned1 to the yellow product obtained by treatment of the isothiouronium salt (I1 ; n = 1) with aqueous sodium hydrogen carbonate and phenyl isothiocyanate, has been confirmed by X-ray crystallography.

Unfolding BOB Bonds for an Enhanced ORR Performance in ABO3‐Type Perovskites

“…The benchmark Pt/C data read from the literature is used as a reference. [23] Although the overpotentials of these perovskites are munch large than that of Pt/C, it has been proved by Shao-Horn and co-workers that their ORR kinetics is comparable to state-of-the-art Pt/C. [15] Here, similar Tafel slopes could also be found in this work.…”

“…, where i L is the limited current. [23] The BET surface areas have been shown in Figure S5 of the Supporting Information. They were used as oxide surface areas to normalize the current density in the Tafel plots.…”

Selective and Efficient Iridium Catalyst for the Reductive Amination of Levulinic Acid into Pyrrolidones

“…This catalyst was efficient at 80 °C but required a high catalyst loading (1 mol%) and did not tolerate bulky amines. Efficient Cp*Ir catalysts were later reported by Xiao [14] and Zhang. [15] These catalyst operated in water under mild conditions (80 °C) by transfer hydrogenation using a formic acid/sodium formate mixture and hydrogenation, respectively.…”

Structure of bis(diphenyl phosphato)tetrakis(imidazole)copper(II), [Cu{P(C6H5O)2O2}2(C3H4N2)4]

“…For symmetry reasons the atoms Cu, N(1), N(3), N(I ~) and N(3 ~) are coplanar; above and below this plane O atoms from two diphenyl phosphate molecules are symmetrically placed and complete the tetragonally distorted (elongated, 4 + 2) octahedral coordination. The Cu-O(phosphate)ax distances of 2.556 (2)A are considerably greater than those found for Cu-O(phosphate)eq bonds in such crystal structures as [ Cu(3'-GM P)(phen)(H 20)12.7H20, [Cu(5'-CMP)(dpa)-(H20) ]2.5H20 (dpa = 2,2'-dipyridylamine), and [Cu(ATP)(phen)]2.7H20, where the Cu-O distances are 1.929, 1.94 and 1.97 (average values), and 1.919-1.977A, respectively (Wei, Fischer & Bau, 1978;Aoki, 1979;Sheldrick, 1981).…”
