A new modification of the Friedlander synthesis via ortho-dilithiated N-pivaloylanilines was written by Ubeda, J. Ignacio;Villacampa, Mercedes;Avendano, Carmen. And the article was included in Synlett in 1997.Safety of N-(3-Methoxyphenyl)pivalamide This article mentions the following:
Formylation of ortho-dilithiated N-pivaloylanilines followed by treatment with carbonyl compounds and KHMDS affords 3- or 2,3-substituted quinoline derivatives in a one-pot reaction. In the experiment, the researchers used many compounds, for example, N-(3-Methoxyphenyl)pivalamide (cas: 56619-93-3Safety of N-(3-Methoxyphenyl)pivalamide).
N-(3-Methoxyphenyl)pivalamide (cas: 56619-93-3) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Safety of N-(3-Methoxyphenyl)pivalamide
