Abstract

Organic solvent nanofiltration (OSN) is gradually expanding from academic research to industrial implementation. The need for membranes with low and sharp molecular weight cutoffs that are able to operate under aggressive OSN conditions is increasing. However, the lack of comparable and uniform performance data frustrates the screening and membrane selection for processes. Here, a collaboration is presented between several academic and industrial partners analyzing the separation performance of 10 different membranes using three model process mixtures. Membrane materials range from classic polymeric and thin film composites (TFCs) to hybrid ceramic types. The model solutions were chosen to mimic cases relevant to today's industrial use: relatively low molar mass solutes (330–550 Da) in n-heptane, toluene, and anisole.

Abstract

Despite the prolific use of (di-)NHC complexes in homogeneous catalysis, there are relatively few reports on their successful application in asymmetric transformations. In this work the atropisomeric binaphthyl backbone was combined with readily obtainable 1,2,3-triazolylidenes to develop a strongly electron-donating C2-symmetric ligand. The ligand was efficiently synthesized in a three-step procedure in an overall yield of 91 % starting from commercially available materials. Strategies for the synthesis of the corresponding di-NHC silver(I), palladium(II), rhodium(I), and iridium(I) complexes have been developed. The rhodium(I) complex was employed in the catalytic asymmetric hydrosilylation of ketones, providing good conversions at catalyst loadings as low as 0.2 mol-% and giving chiral inductions of up to 51 % ee.

Abstract

1,2,3-Triazol-5-ylidenes(tzNHC) have become a popular class ofNHC ligands in homogeneous catalysis. Herein, we introduce chelatemonovalent Rh- and Ir(cod) complexes bearing bidentate ligands thatcombine this tzNHC and an Arduengo-type NHC motif. The reactivityof these complexes with H2and CO gas has been investigated,leading to an interesting octahedral [Ir(tzNHC-CH2-NHC)(CO)2(H)2]OTf complex and [M(tzNHC-CH2-NHC)(CO)2]OTf complexes. The carbonyl stretching frequencies of thelatter indicate that the ligand has stronger electron-donating propertiesthan classic di-NHC ligands. The square planar rhodium and iridiumNHC-tzNHC complexes have been applied in transfer hydrogenation employingisopropyl alcohol as the hydrogen donor, in which they show moderateactivity (Ir > Rh) toward a range of ketones as well as for analdehyde,an imine, and a diene. The new dicarbene complexes proved to be moreactive for this reaction than the analogues in which the triazolylmoiety coordinates through a nitrogen donor. [ABSTRACT FROM AUTHOR]
