Periodic Reporting for period 2 - ReNewHydrides (Renewable Hydride Donors and Their Utilization in Catalytic Reduction and Deoxygenation Reactions)
Período documentado: 2021-04-01 hasta 2022-09-30
Today, no reduction method meets the criteria for a versatile and energy efficient reduction of oxidized feedstocks and the aim of the ReNewHydrides project is to design novel reductants and catalytic reactions to achieve this important aim. At the crossroads of main group element chemistry, organometallic chemistry, electrochemistry and homogenous catalysis, the teams develops innovative and recyclable reductants based on silicon and boron compounds, which are further utilized to tackle catalytic challenges in the reduction of C–O, N–O
P–O and Si–O bonds. The overarching principle is to build a balanced synthetic cycle, where the electrochemical reduction of functionalized and oxidized substrates is ensured by silicon and boron based hydride donors, with a high energy efficiency and selectivity.
The project is divided is two complementary strands: while Strand 1 focuses on the development of renewable hydride donors based on silicon and boron, Strand 2 will explores the uses of these new reductants in the reduction of C–O, N–O
P–O and Si–O bonds where H2 utilization fails.
- A proof-of-concept for the electrochemical generation of hydrosilanes and hydroboranes, with the design of a suitable cell and cathodic catalysts
- The demonstration that amines can be homologated using cascade reductive carbonylation, in order to generate long chain aliphatic amines which are useful molecules in the formulation of detergents
- Opening the reactivity of silyl and boryl formates through catalysis for the transfer- hydrosilylation and hydroboration of esters and phosphine oxides.
