Contra-Thermodynamic Chain-Walking Isomerization: A Sustainable Tool for Selective Molecular Editing in Green Chemistry. [PDF]

ChemSusChem
Contra‐thermodynamic chain‐walking isomerization enables selective migration of alkenes to less stable yet synthetically valuable terminal position under mild, catalytic conditions. By integrating tailored metal catalysis, photochemical, and redox strategies, this approach affords efficient access to terminal and remote functionalized products with ...

Examination of Milstein Ru-PNN and Rh-Tribi/Tetrabi dual metal catalyst for isomerization-linear-hydroformylation of C4 raffinate and internal olefins

Green Synthesis and Catalysis, 2022
Isomerization-linear-hydroformylation is demanding, however, not an addressed issue, for production of value-added linear aldehydes by converting cheap and abundant internal alkenes available from bio- & petrochemical industry.

Phosphorus coordinated Rh single-atom sites on nanodiamond as highly regioselective catalyst for hydroformylation of olefins

Nature Communications, 2021
Single-atom Rh catalysts present superior activity in olefins hydroformylation, yet with limited success in regioselectivity control. Here the authors develop a Rh1 single-atom catalyst with nanodiamond as support, with which good to excellent ...

How the coordination modes change the performance of Rh-PPh3 for complexes catalyst allyl alcohol hydroformylation: A theoretical study

Catalysis Communications, 2023
This paper investigates the effect of coordination modes on the selectivity and activity of hydroformylation catalysts using Rhodium complexes. DFT calculations are performed on monophosphine (1P) and bisphosphine (2P) catalysts to study the impact of ...

Reductive Hydroformylation of Isosorbide Diallyl Ether

Molecules, 2021
Isosorbide and its functionalized derivatives have numerous applications as bio-sourced building blocks. In this context, the synthesis of diols from isosorbide diallyl ether by hydrohydroxymethylation reaction is of extreme interest.

Metal-organic frameworks as kinetic modulators for branched selectivity in hydroformylation

Nature Communications, 2020
The Co-catalysed hydroformylation of olefins produces selectively linear but not branched aldehydes. Here, the authors show that microporous MOFs increase the olefins density in the pores beyond neat conditions allowing high branched selectivity through ...

An Intramolecular Hydroaminomethylation-Based Approach to Pyrrolizidine Alkaloids under Microwave-Assisted Heating

Molecules, 2022
A general method for the synthesis of pyrrolizidine derivatives using an intramolecular hydroaminomethylation protocol (HAM) under microwave (MW) dielectric heating is reported. Starting from a 3,4-bis(benzyloxy)-2-[(benzyloxy)methyl]-5-vinylpyrrolidine,
