4-Bromo-N-methoxy-N-methylbenzamide (cas: 192436-83-2) belongs to amides. Compared to amines, amides are very weak bases and do not have clearly defined acid–base properties in water. On the other hand, amides are much stronger bases than esters, aldehydes, and ketones. Amides are not in general accessible by the direct condensation of amines with carboxylic acids for two reasons: first, both components are readily deactivated by a transfer of a proton from the acid to the amine and second, the hydroxy unit on the carbonyl of the acid is a relatively poor leaving group. Nevertheless, the formation of five- and six-membered rings is often surprisingly simple provided that other factors can be brought into play to assist in the condensation.HPLC of Formula: 192436-83-2

Visible light mediated synthesis of 4-aryl-1,2-dihydronaphthalene derivatives via single-electron oxidation or MHAT from methylenecyclopropanes was written by Liu, Jiaxin;Wei, Yin;Shi, Min. And the article was included in Organic Chemistry Frontiers in 2021.HPLC of Formula: 192436-83-2 This article mentions the following:

A direct single-electron oxidation of methylenecyclopropanes (MCPs) I (R = H, 2-Me, 3-OMe, 4-F, etc.; R1 = H, 2-Me, 3-Cl, 4-F, etc.) for the rapid construction of 4-aryl-1,2-dihydronaphthalene derivatives II (R2 = H, 5-Me, 6-OMe, 7-F, etc.; R3 = H, F) and III (R4 = R5 = H, F) by merging visible light photoredox catalysis and cobalt catalysis was reported. In MeCN with Et3N·3HF (1.0 equivalent), the fluorination of MCPs I can be realized in the presence of 9-mesityl-10-methylacridinium perchlorate and Co(dmgH)2PyCl, affording fluorinated 4-aryl-1,2-dihydronaphthalene derivatives II (R3 = F) in moderate yields. In MeCN/HFIP (7 : 3), 4-aryl-1,2-dihydronaphthalene derivatives II (R3 = H) and III were obtained in good yields through a metal-catalyzed hydrogen atom transfer process under similar conditions. In the experiment, the researchers used many compounds, for example, 4-Bromo-N-methoxy-N-methylbenzamide (cas: 192436-83-2HPLC of Formula: 192436-83-2).
