efficient palladium-catalyzed anti-Markovnikov oxidative acetalization of activated terminal olefins with iron(III) sulfate as the reoxidant. This methodology requires mild reaction conditions and shows high regioselectivity toward anti-Markovnikov products and compatibility with a wide range of functional groups. Iron(III) sulphate was the sole reoxidant used in this method. Various olefins like vinylarenes
本文公开了以硫酸铁( III )为再氧化剂的活性末端烯烃的高效钯催化抗马尔科夫尼科夫氧化缩醛化反应。该方法需要温和的反应条件,并显示出对抗马尔科夫尼科夫产物的高区域选择性以及与多种官能团的相容性。硫酸铁( III ) 是该方法中使用的唯一再氧化剂。各种烯烃,如乙烯基芳烃、芳基烯丙基醚、丙烯酸芳基或苄基丙烯酸酯和高烯丙醇都反应良好,提供抗马尔科夫尼科夫缩醛,其中一些代表正交官能化的 1,3-和 1,4-二氧化化合物。

different conditions for the three-component reaction of N′-(2-alkynylbenzylidene)hydrazide, α,β-unsaturated carbonylcompound, with bromine. 6-BromoH-pyrazolo[5,1-a]isoquinoline was obtained when the reaction was performed in NMP at 70 °C in the presence of DABCO as base, while 6-bromo-1,2,3,10b-tetrahydropyrazolo[5,1-a]isoquinoline was afforded when the reaction occurred in DMAc at 10 °C in the presence
N '-(2-炔基亚苄基)酰肼,α,β-不饱和羰基化合物与溴的三组分反应在不同条件下产生了不同的结果。当以DABCO为碱在70°C下于NMP中于NMP中进行反应时,获得了6-溴H-吡唑并[5,1- a ]异喹啉,而6-溴-1,2,3,10 b-四氢吡唑并已获得了6-溴H-吡唑并[5,1- a ]异喹啉。当反应在10 K的DMAc中以K 3 PO 4为碱存在时,提供[5,1- a ]异喹啉。

Provided is a curable resin composition comprising a thermoplastic resin (A) that includes a cyclic structure in its main chain, and has a glass transition temperature (Tg) of 140° C. or more, and a monofunctional curable monomer (B). The present invention provides: a cured resin formed article that has heat resistance and low birefringence, a method for producing the same, a curable resin composition and a curable resin formed article that are useful as a raw material for producing the cured resin formed article, and a laminate that includes a layer formed of a cured resin.
A photoinduced TBADT-catalyzed one-pot, three-component strategy for the synthesis of alkyl-alkyl sulfones was reported. The developed methodology could tolerate broad functional groups and allow for the late-stage modification of complex molecules.
