Cobaltate anion couples terminal dienes with trifluoroacetic anhydride: a direct fluoroacylation of 1,3-dienes was written by Kohn, Benjamin L.;Rovis, Tomislav. And the article was included in Chemical Science in 2014.Application of 79-55-0 This article mentions the following:
Cobalt-mediated fluoroacylation of 1,3-dienes using perfluorinated anhydrides such as TFAA was described. The reaction proceeded through a fluoroacylcobalt reagent which formed in-situ. Perfluoroacylation of 1,3 dienes was also performed to attain longer chain perfluorinated ketones. In the experiment, the researchers used many compounds, for example, 1,2,2,6,6-Pentamethylpiperidine (cas: 79-55-0Application of 79-55-0).
1,2,2,6,6-Pentamethylpiperidine (cas: 79-55-0) belongs to piperidine derivatives. The piperidine structural motif is present in numerous natural alkaloids. These include piperine, which gives black pepper its spicy taste. Piperidine derivatives bearing a masked aldehyde function in the 蔚-position are easily transformed into quinolizidine compounds through intramolecular reductive amination.Application of 79-55-0
