B(C 6 F 5)3催化的氢化作用适用于带有易于去除的邻苯二甲酰基保护基的乙二肟三异丙基甲硅烷基醚和。醛衍生的底物(肟醚和as)的CN还原可通过使用1,4-二恶烷作为已知参与FLP型杂二氢裂解的路易斯碱组分的溶剂来实现。在FLP型二氢活化中,更多的碱性酮衍生的azo酮充当Lewis碱本身,因此在不给体的甲苯中成功氢化。醛和酮衍生的底物之间的反应性差异也反映在所需的催化剂负载量和二氢压力上。

Prochiral hydrazones undergo efficient and highly selective hydrogenation in the presence of a chiral diphosphine ruthenium catalyst, yielding enantioenriched hydrazine products (up to 99% ee). The mild reaction conditions and broad functional group tolerance of this method allow access to versatile chiral hydrazine building blocks containing aryl bromide, heteroaryl, alkyl, cycloalkyl, and ester substituents

atom‐economic way to prepare alkylamines, ideally with water as the sole byproduct. Herein, nickel catalysts are used for direct N‐alkylation of hydrazides and arylamines using racemic alcohols. Moreover, a nickel catalyst of (S)‐binapine was used for an asymmetric N‐alkylation of benzohydrazide with racemic benzylic alcohols.
In the present invention, the two-pack type curable resin composition using a compound having one or more (meth)acrylic groups in the molecule enables both of prolongation of a working life and maintenance of physical properties of a cured product. Prior art had a difficulty in controlling a working life continuously; however, the present invention can easily control the working life and therefore makes it possible to be used in various conditions. Provided is a two-pack type curable resin composition, containing components (A) to (E): component (A) being a compound having one or more (meth)acrylic groups in the molecule thereof; component (B) being hydroperoxide; component (C) being at least one type of copper compound and vanadium compound; component (D) being a compound having 2 to 6 thiol groups in the molecule thereof; and component (E) being saccharin.
An object of the present invention is to provide a curable resin composition having low viscosity and being capable of forming a cured product which is excellent in the flexibility and the heat resistance.
The present invention is a curable resin composition including:
a (meth)acrylic group-containing vinyl-based polymer (A), a monomer (B) represented by the following Chemical formula (1), and a radical initiator (C).
