The synthesis of heterogenous Co‐MOFs and application in the catalytic hydrosilylation of alkenes

Abstract

Hydrosilylation employing metal-organic frameworks (MOFs) as the catalyst are promising because of their high catalytic reactivity and sustainability of heterogeneous catalyst. A highly simple and efficient method for the hydrosilylation of olefins catalyzed by an air-stable MOF-cobalt catalysts is developed. This approach is featured by 0.1% of Co-MOFs catalyst with excellent reactivity, recyclability, and good functional group tolerance. The Co-MOFs can catalyze hydrosilylation of styrene or its derivatives with Ph 2 SiH 2 in the presence of NaBHEt 3 . Moreover, the catalysts we developed show excellent stability, and the activity is not significantly reduced after repeating the cycle for five times.

Historical and contemporary perspectives on metal–organic frameworks for gas sensing applications: a review

“…229,230 Therefore, we predict increased potential of user-synthesized MOFs to be included as a template for a carbon-neutral cycle positively offset by industrial emissions, 231,232 with such frameworks possessing better transportation and recyclability, 233 as well as potential to catalyze and reduce the carbon footprints emitted from non-industrial sites and transform them into green and clean molecules 234 for a better and more sustainable environment. 235,236…”

Catalytic hydrosilylation using an immobilized Co-terpyridine complex activated by inorganic salts and its application in a flow reactor

“…19 By contrast, base metal complexes for hydrosilylation that are immobilized on a stationary phase are limited. 20,21 Recently, our group developed a Co complex supported on silica gel ( Co(tpy)(X) 2 @SiO 2 , where X = OH, Br) in which a Co complex with terpyridine (tpy), being one of the simplest pincer ligands, was immobilized on the surface of silica gel or glassware. 22 Co(tpy)Br 2 @SiO 2 (a rough image of the silica gel surface supporting Co(tpy)Br 2 is shown in Fig.…”
