The transition metal catalyzed hydrogenation of alkenes is a well-developed technology used on lab scale as well as on large scales in the chemical industry. Site- and chemoselective mono-hydrogenations of polarized conjugated dienes remain challengi

The complex Ru-MACHO has been previously shown to undergo uncontrolled degradation subsequent to base-induced dehydrochlorination in the absence of a substrate. In this study, we report that stabil...

Palladium-Catalyzed Low Pressure Carbonylation of Allylic Alcohols by Catalytic Anhydride Activation
Publikováno v:
Chemistry (Weinheim an der Bergstrasse, Germany). 27(36)
A direct carbonylation of allylic alcohols has been realized for the first time with high catalyst activity at low pressure of CO (10 bar). The procedure is described in detail for the carbonylation of E-nerolidol, an important step in a new BASF-rou

The complex Ru-MACHO (1) is a widely used precatalyst for hydrogenation and dehydrogenation reactions under basic conditions. In an attempt to identify the active catalyst form, 1 was reacted with a strong base. The formation of previously unreported

The ruthenium-triphos and diphosphine-catalysed amination of alcohols with ammonia is reported. Various types of triphos derivatives with electron-donating functional group were synthesized and used as ligands in the Ru-catalysed alcohol amination wi

An active and selective system for the amination of primary alcohols to primary amines with ammonia based on ruthenium and triphos as the tridentate phosphine ligand was developed. On the basis of detailed mechanistic studies, we propose that the act

We herein describe the first synthesis of iminosugar C-glycosides of α-D-GlcNAc-1-phosphate in 10 steps starting from unprotected D-GlcNAc. A diastereoselective intramolecular iodoamination-cyclization as the key step was employed to construct the c

The use of aminoacidato Cp*Ir(III)-complexes in catalytic alcohol amination reactions of primary and secondary alcohols with amines permits to carry out these transformations at very mild reaction ...
