The efficient conversion of methane into methanol at low temperature under low pressure remains a great challenge largely because of the inertness and poor solubility of methane. Herein, we report that a porous organic polymer-supported Pd catalyst, which was constructed via Friedel-Crafts type polymerization between 4,6-dichloropyrimidine and 1,3,5-tri-Ph benzene and subsequent metalation, enabled the conversion of methane to Me trifluoroacetate, a precursor to methanol, under atm. pressure (1 atm) at 80°C to afford a 51% yield relative to methane with a TON of 664 over 20 h. On increasing the pressure to 30 bar, this palladium catalyst offered a TON of 1276 for a run and could be reused for at least five runs without a notable loss of activity. The characterization of this Pd catalyst revealed its good affinity for methane uptake that would increase the concentration of methane in the local space around the Pd center and the homogeneous distribution of Pd2+ on support that would protect the catalytically active metal species, shedding light on the high catalytic activity of this Pd catalyst toward methane conversion. The experimental process involved the reaction of 4,6-Dichloropyrimidine(cas: 1193-21-1Recommanded Product: 1193-21-1)
4,6-Dichloropyrimidine(cas: 1193-21-1) is a member of organic chlorides. Organic chloride content in crude oil can be detected through specialized laboratory analysis. Care and attention are essential while sampling and testing.Recommanded Product: 1193-21-1
