Xia, Biao; Chen, Wenjun; Zhao, Qiongli; Yu, Wenquan; Chang, Junbiao published the artcile< Synthesis of Functionalized Imidazolium Salts via Iodine-Mediated Annulations of Enamines>, SDS of cas: 94-02-0, the main research area is imidazolium salt preparation; enamine preparation annulation iodine.

A novel annulation reaction of two enamine mols. with iodine under basic conditions to form 4-functionalized imidazolium salts has been established. In this reaction, iodine acts as both an iodinating reagent and a Lewis acid catalyst. Features of this synthetic method include facilitative preparation of substrates, no use of transition metals, mild reaction conditions, simplicity of operation, and gram scale synthesis.

Organic Letters published new progress about Cyclization. 94-02-0 belongs to class esters-buliding-blocks, and the molecular formula is C11H12O3, SDS of cas: 94-02-0.

Tri-carbonylated oxiranes I [R = H; Ar = Ph, 4-MeC6H4, 4-BrC6H4, etc.] were efficiently synthesized via condensation of vicinal tricarbonyl compound with α-bromoketones in the presence of a base. This protocol was applicable to α-bromo-β-keto esters to give tetra-carbonylated oxiranes I [R = CO2Et] from which trifunctionalized bromoalkene was competitively formed. The ratio of compounds I was influenced by the solvent and reaction temperature Synthesis of 2,3-bis-organochalcogenyl-benzo[b]chalcogenophenes promoted by oxone.

Zhang, Heng; Guo, Tianyun; Wu, Mingzhong; Huo, Xing; Tang, Shouchu; Wang, Xiaolei; Liu, Jian published the artcile< 4CzIPN catalyzed photochemical oxidation of benzylic alcohols>, Reference of 94-02-0, the main research area is aldehyde ketone preparation green chem 4CzlPN catalyst; benzylic primary secondary alc photoredox oxidation.

A green photoredox oxidation of benzylic primary and secondary alcs. to aldehydes and ketones with air as an oxidant was reported. The oxidation shows broad substrate scope and excellent selectivity over benzylic alcs. to the aliphatic alcs. Further mechanistic studies revealed a quinuclidine mediated HAT process, and blue LEDs promoted 4CzlPN (1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene) photoredox cycle were involved in the oxidation
