  • Experimental and Theoretical Investigation of the Reaction of Secondary Amines with Maleic Anhydride
    作者:Manjinder Kour、Raakhi Gupta、Raj K. Bansal
    DOI:10.1071/ch17206
    日期:——
    The reaction of secondary amines, namely 1-methylpiperazine, pyrrolidine, morpholine, 2-methylpiperidine, and diethylamine, with maleic anhydride has been investigated experimentally and theoretically at the DFT level. Under kinetic control, i.e. at −78°C or −15°C, amines add across the C=O functionality exclusively and the initially formed addition products isomerize to the corresponding N-substituted
    已在DFT级别上通过实验和理论研究了仲胺(即1-甲基哌嗪,吡咯烷,吗啉,2-甲基哌啶和二乙胺)与马来酸酐的反应。在动力学控制下,即在-78°C或-15°C下,胺仅跨C = O官能团加成,初始形成的加成产物异构化为相应的N-取代的马来酸衍生物。与无环的α,β-不饱和羰基化合物相反,即使在热力学控制下,胺也不会在C = C官能团中加成胺。可以基于局部稠合的Fukui功能来合理化马来酸酐的这种行为,这表明马来酸酐中的羰基碳原子比无环α,β-不饱和羰基化合物如丙烯醛中的硬得多。

  • Latently-curable organosilicone release coating composition
    申请人:MINNESOTA MINING AND MANUFACTURING COMPANY
    公开号:EP0140530A1
    公开(公告)日:1985-05-08
    A latently-curable, organosilicone composition comprises a metal catalyzed organosilicone composition capable of undergoing hydrosilation and, as hydrosilation inhibitor, an organic monohydrogen derivative of an unsaturated aliphatic 1,4-dicarboxylic acid, i.e., maleic acid or acetylene dicarboxylic acid. The organic monohydrogen derivatives of use in this invention effectively inhibit catalyzed hydrosilation reactions at low or room temperature while allowing efficient hydrosilation reaction rates to occur at elevated temperatures. These monohydrogen derivatives perform their inhibitive function effectively at low concentration. The latently curable composition may be coated on a substrate to provide a release surface for an adjacent adhesive layer.
