alkylating reagents, alkyl etherification of olefins with generalalkyl groups has not been previously reported. In this work, a variety of alkyl diacyl peroxides and peresters generated from aliphatic acids have been found to enable the first iron‐catalyzed alkyl etherification of olefins with generalalkyl groups. Primary, secondary and tertiary aliphatic acids are suitable for this reaction, delivering products
The present invention has its object to provide a thermoplastic resin for producing moldings having enough transparency and excellent in permanent antistatic properties and mechanical properties. The present invention provides a transparent resin composition which comprises at least one block polymer (A) selected from the group consisting of specific block polymers (A1) and (A2) and a transparent resin (B), with the difference in refractive index between (A) and (B) being not more than 0.01.
Alkyl diacyl peroxides were demonstrated to be efficient alkylating reagents for the visible-light-induced 4CzIPN-catalyzed direct C–H alkylation of N-heteroaromatics. With this metal-/base-/additive-free photocatalytic system, 57 examples of alkylated N-heteroaromatics scaffolds including 1,2,4-triazine-3,5(2H,4H)-diones (i.e. azauracils), quinoxalin-2(1H)-ones, 2H-benzo[b][1,4]oxazin-2-ones and quinoxalines
烷基二酰基过氧化物被证明是可见光诱导的 4CzIPN 催化的N-杂芳烃直接 C-H 烷基化的有效烷基化试剂。利用这种不含金属/碱/添加剂的光催化系统,57个烷基化N-杂芳族化合物支架的例子包括1,2,4-三嗪-3,5(2 H ,4 H )-二酮(即氮尿嘧啶)、喹喔啉-成功合成了2(1 H )-酮、2 H-苯并[ b ][1,4]恶嗪-2-酮和喹喔啉。
