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. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.HPLC of Formula: 56619-93-3

π-Excess σ2P,O hybrid ligands: synthesis of the first 4-methoxy-1H-1,3-benzazaphospholes was written by Aluri, Bhaskar R.;Jones, Peter G.;Dix, Ina;Heinicke, Joachim W.. And the article was included in Synthesis in 2014.HPLC of Formula: 56619-93-3 This article mentions the following:

3-Pivaloylaminoanisole undergoes regioselective lithiation in 2-position, which enables introduction of phosphono and phosphino-groups in 2-position; the reduction product, phosphine 3-MeO-2-PH2-1-NHCH2tBuC6H3 was cyclized into 1-neopentyl-4-methoxy-1H-1,3-benzazaphosphole with 86% yield. The synthesis of the first 4-methoxy-substituted 1,3-benzazaphosphole was accomplished by using a C,O-dilithium intermediate generated from N-(3-methoxyphenyl)-2,2-dimethylpropanamide and butyllithium. This intermediate was subjected either to direct phosphonylation or to a bromination and phosphonylation sequence; subsequent reductive cyclization with excess lithium aluminum hydride led to the desired product. In addition, N-(2,2-dimethylpropyl)-3-methoxy-2-phosphinoaniline, formed in a side reaction, was cyclized with (dimethoxymethyl)dimethylamine to give 1-(2,2-dimethylpropyl)-4-methoxy-1H-1,3-benzazaphosphole. The behavior of these +M-substituted π-excess aromatic σ2-P-heterocycles towards moisture is reported, together with their 1H, 13C, and 31P solution NMR spectra and a crystal-structure anal. The new compounds represent potential σ2-P,O hybrid or chelate ligands with a high π-d. at the phosphorus atom. In the experiment, the researchers used many compounds, for example, N-(3-Methoxyphenyl)pivalamide (cas: 56619-93-3HPLC of Formula: 56619-93-3).
