N-formylation of amines with CO2 and hydrosilane reducing agents proceeds via fast and complex chemical equilibria, which hinder easy analysis of the reaction pathways. In situ reaction monitoring and kinetic studies reveal that three proposed pathways, vi ...

Towards a frustrated Lewis pair-ionic liquid system

Paul Joseph Dyson, Rosario Scopelliti, Gabor Laurenczy, Zhaofu Fei, Felix Daniel Bobbink, Emilia Paunescu, Florian Gérald Abela

An ionic liquid encompassing a bulky tertiary amine was synthesized and used as a dual solvent-reactant for the formation of a frustrated Lewis pair with tris(pentafluorophenyl) borane, forming a pseudo-frustrated Lewis pair-ionic liquid system. The ionic ...

Dehydrogenation of Formic Acid over a Homogeneous Ru-TPPTS Catalyst: Unwanted CO Production and Its Successful Removal by PROX

Gabor Laurenczy, Nordahl Autissier, Veronica Henricks

Formic acid (FA) is considered as a potential durable energy carrier. It contains ~4.4 wt % of hydrogen (or 53 g/L) which can be catalytically released and converted to electricity using a proton exchange membrane (PEM) fuel cell. Although various catalyst ...

Method for producing methanol from carbon dioxide and hydrogen gas in homogeneously catalyzed reactions and in an aqueous medium

Gabor Laurenczy, Katerina Stefania Sordakis

The invention relates to a method for producing methanol from hydrogen and carbon dioxide gas in homogeneously catalyzed reactions, composed of the carbon dioxide hydrogenation reaction to formic acid and the formic acid disproportionation reaction into me ...

Formic Acid as a Hydrogen Carrier for Fuel Cells Toward a Sustainable Energy System

Gabor Laurenczy

Formic acid is considered as one of the promising organic liquid hydrogen carriers for the next generation; it can offer a viable method for safe hydrogen transport. In this chapter, we introduce the potential of formic acid in terms of thermodynamics and ...

CO2 as hydrogen vector - Transition metal diamine catalysts for selective HCOOH dehydrogenation

Gabor Laurenczy, Cornel Fink

The homogeneous catalytic dehydrogenation of formic acid in aqueous solution provides an efficient in situ method for hydrogen production, under mild conditions, and at an adjustable rate. We synthesized a series of catalysts with the chemical formula [Cp* ...

Ionic liquids (ILs) are versatile solvents and catalysts for the synthesis of quinazoline-2,4-dione from 2-aminobenzonitrile and CO2. However, the role of the IL in this reaction is poorly understood. Consequently, we investigated this reaction and showed ...

A versatile palladium-catalyzed double carbonylation of aryl bromides has been developed. Using Pd(OAc)2/BuPAd2 as the catalyst system and DBU as the base, under relatively low CO pressure, various a-ketoamides were produced in good yields. In order to get ...

Production of methanol (MeOH) from CO2 is strongly desired as a key chemical feedstock and a fuel. However, the conventional process requires elevated temperature and pressure, and high temperature restricts the productivity of MeOH due to equilibrium limi ...

Herein we describe formic acid disproportionation into methanol with a homogeneous iridium catalyst. Methanol yields of up to 74% were obtained in D2O at 50 °C. Initial H2 pressures further enhanced methanol formation, resulting in a highly concentrated 9. ...
