  直接苄基 C(sp3)–O 通过位点选择性 C(sp3)–H 裂解在室温下通过远程引导基团启用自由基中继策略与醇偶联

  摘要：

  采用低负载的末端氧化剂，开发了一种在室温下与醇直接进行苄基直接 C(sp 3 )-H 烷氧基化的远程导向基团自由基中继策略。在简单温和的条件下实现了令人满意的位点选择性、化学选择性和反应范围，无需配体或添加剂。我们实验室目前正在开发的机械研究、导向基团的现成转换和其他苄基官能化进一步表明了这种远程导向基团激活的自由基中继策略的潜力。

  α-Azidobenzyl ethers were reacted with alkyl or arylGrignard reagents in toluene to produce α-alkylbenzyl or diarylmethyl ethers in 82–94% yield. α-Azidobenzyl ethers were also reacted with multicomponent Grignard reagents to produce libraries of α-alkylbenzyl ethers.

  在甲苯中，α-叠氮苄基醚与烷基或芳基格氏试剂反应，以82-94%的产率生成α-烷基苄基醚或二芳基甲基醚。α-叠氮苄基醚还可以与多组分格氏试剂反应，生成α-烷基苄基醚的库。

  An additive composition for making polyurethane foam where the additive composition is defined as at least one compound selected from the following groups: a. Aromatic ethers of general formula R-(CH2)x-Z-(CH2)y-R' where R = substituted or unsubstituted aryl group; Z = O or R"-N with R" = Ci-C8 alkyl group, and preferentially methyl or benzyl; x = 0-3; y = 0-3; and R' = substituted or unsubstituted aryl group where the substituents are non- isocyanate reactive groups or a Ci-C8 alkyl group; b. Aromatic ethers of general formula R-O-Aryl-O-R' where R = C1-C6 hydrocarbon; R' = CrC6 hydrocarbon; and aryl = alkyl/aryl substituted or unsubstituted where the substituents are non-isocyanate reactive groups; c. Aromatic esters of general formula R-02C-Aryl-C02-R' where R = CrC6 hydrocarbon; R' = CrC6 hydrocarbon; and aryl = substituted or unsubstituted aryl group where the substituents are non-isocyanate reactive groups; and d. Substituted aromatic compounds of the general formula Rx-Aryl where R = Ci-C6 hydrocarbon; x = 1 -6; and aryl = substituted or unsubstituted aromatic derived from benzene, naphthalene, anthracene, or phenanthrene. A polyurethane composition and method for forming a polyurethane foam is also disclosed.
