4-Chloro-3-Methyl-N,N-Dimethylaniline 以 异丙醇 用作溶剂,化学反应 30.0H,以89%的收率获得n,N-二甲基-间甲基苯胺 参考文献:Solarylations Via 4-Aminophenyl Cations 标题:Solarylations Via 4-Aminophenyl Cations 摘要:The Application Of The Photo-S(N)1 Reaction On Sonic 4-Chloroanilines Was Explored Under Solar Irradiation In View Of Obtaining A Convenient Metal-Free Arylation Method. Several Reactions Previously Carried Out By Uv Irradiation,As Well As Some New Ones,Where Either A New Trap (Alpha-Methylstyrene) Ora New Halide (N,N-Dimethyl-4-Fluoroaniline) Were Adopted,Were Studied Under These Conditions And Found To occur Conveniently. Furthermore,At Least In Some Cases The Halide Starting Concentration Could Be Raised Up To 0.2 M,The Excess Trapping Agent Reduced From 20:1 To 2.5:1,And The Solvent Replaced By More Environmentally Friendly (Co)Solvents Including Water. Under These Improved Conditions,The Photoarylation Was Carried Out In A Gram Scale By Merely Exposing The Solution To Solar Irradiation. This Process Has A Low Impact On The Environment And Can Be Considered A Serious Competitor Of Metal-Catalyzed Arylations. Doi:10.1021/jo902669J

专利号:US-2024100563-A1 优先权日:2020-10-14 标 题 :Enhanced copolymer synthesis methods and applications thereof 发明人:WYATT QUINTON K; YOUNG MATTHIAS J; KINLEN PATRICK J; PARANAMANA NIKHILA C 权利人:UNIV MISSOURI 摘要:Unique polymers and copolymers generated via oMLD processes are described alongside the methods for tuning such polymer and copolymer structures and redox chemistries. The polymers and copolymers described can incorporate monomeric species previously held to have too high an oxidation potential for successful use in oMLD, can exhibit unexpected redox chemistry from the adjustable incorporation of primary amine monomers and resulting azo functional groups, and show superior performance metrics when compared to polymers and copolymers synthesized by other methods. Applications for these polymers and copolymers are also described.
