On April 27, 2020, Shaikh, Aslam C.; Veleta, Jose M.; Bloch, Jan; Goodman, Hannah J.; Gianetti, Thomas L. published an article.Name: Methyl 2-cyclopentanonecarboxylate The title of the article was Syntheses of Phosphonium Salts from Phosphines and Carbenium: Efficient CO2 Fixation and Phase-Transfer Catalysts. And the article contained the following:
A new library of phosphonium salts was synthesized from the reaction of tris-(2,6-dimethoxyphenyl)carbenium with different phosphines. The resultant phosphonium salts work as efficient phase-transfer catalysts for the alkylation of 1,3-dicarbonyl compounds One compound, a bifunctional phosphonium salt prepared from tris-(2,6-dimethoxyphenyl)carbenium and an aminophosphine, also is an efficient catalyst for CO2 fixation reactions with epoxides under mild conditions. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Name: Methyl 2-cyclopentanonecarboxylate
The Article related to carbeniumphosphonium salt preparation phase transfer catalyst carbon dioxide fixation, phenylcarbenium reaction phosphine, phosphonium carbenium salt preparation catalyst epoxide carbon dioxide fixation, cyclic carbonate preparation, alkylation keto ester carbeniumphosphonium salt phase transfer catalyst, crystal structure triphenylcarbenium phosphonium salt and other aspects.Name: Methyl 2-cyclopentanonecarboxylate
