A unified strategy for silver-, base-, and oxidant-free direct arylation of C-H bonds was written by Sahoo, Manoj K.;Midya, Siba P.;Landge, Vinod G.;Balaraman, Ekambaram. And the article was included in Green Chemistry in 2017.Formula: C12H17NO2 This article mentions the following:
Herein, a dual catalytic approach for room temperature direct arylation of C-H bonds with aryldiazonium salts as a simple aryl group donor, also working as an internal oxidant via C-N2 bond cleavage is reported. This unified strategy has been achieved by the synergistic combination of visible-light metal-free photoredox and palladium catalysis under silver-, base- and/or additive-free conditions. The broad substrate scope, functional group tolerance, excellent regioselectivity and redox-neutral conditions of this process make it attractive for the effective synthesis of a wide range of important N-heterocyclic commodities such as dibenzo[b,d]azepine, carbazole and phenanthridine. In the experiment, the researchers used many compounds, for example, N-(3-Methoxyphenyl)pivalamide (cas: 56619-93-3Formula: C12H17NO2).
N-(3-Methoxyphenyl)pivalamide (cas: 56619-93-3) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. 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.Formula: C12H17NO2
