Bifunctional heterogeneous Ru/POPs catalyst embedded with alkali for the N-formylation of amine and CO2
ACS Sustainable Chemistry & Engineering(2020)
摘要
CO2 as a C1 building block
for the N-formylation reaction
is attracting much attention. In general, the N-formylation reaction
requires the participation of alkali, which can break the equilibrium
to promote the reaction process. We developed a After Ru metalationheterogeneous
catalyst with an alkaline functional group based on a porous organic
polymer (denoted as Ru-PPh3-SO3Na@POPs) by the
copolymerization of vinyl-functionalized PPh3 (3v-PPh3) and sodium-4-vinylbenzenesulfonate. After Ru metalation,
the catalyst obtained a high TON without the addition of alkali under
mild conditions. The Ru-PPh3-SO3Na@POP catalyst
can immobilize metals and alkali efficiently on porous organic polymers,
showing excellent performance and good stability for the N-formylation
reaction of amine and CO2.
