    标题:热解研究.第二十六部分 聚富马酸乙烯酯和相关聚酯热解的模型系统
    摘要:马来酸乙酯的热解导致顺式->反式转化,同时发生烷基-氧断裂(a 1为主),酰基-氧断裂(b 2)和脱羧(c 2).对于马来酸甲酯,在结构上不包括a 1断裂;反之亦然.有顺式->反式反转,同时发生b 2和c 2分裂.二丙烯酸乙烯酯和二甲基丙烯酸乙酯都经历了主要的双c 2断裂,与a 1断裂和较小的竞争b 2断裂:主要的a 1断裂的产物部分相互作用形成亚乙基二酯,随后歧化并进一步分解.所有的热解都在约.气相450-500°.讨论了这些结果对聚富马酸乙烯酯热解的影响.

    标 题 :Metal amides of cyclic amines
    发明人:GORDON ROY GERALD
    权利人:HARVARD COLLEGE
    摘要:Compounds, and oligomers of the compounds, are synthesized with cyclic amine ligands attached to a metal atom. These compounds are useful for the synthesis of materials containing metals. Examples include pure metals, metal alloys, metal oxides, metal nitrides, metal phosphides, metal sulfides, metal selenides, metal tellurides, metal borides, metal carbides, metal silicides and metal germanides. Techniques for materials synthesis include vapor deposition (chemical vapor deposition and atomic layer deposition), liquid solution methods (sol-gel and precipitation) and solid-state pyrolysis. Suitable applications include electrical interconnects in microelectronics and magnetoresistant layers in magnetic information storage devices. The films have very uniform thickness and high step coverage in narrow holes.

    权利人:ESS DANIEL HALSELL; FALCK JOHN RUSSELL; JAT JAWAHAR LAL; KURTI LASZLO
    摘要:A method for the direct stereospecific conversion of structurally diverse mono-, di-, tri- and tetra-substituted olefins to N—H, N-alkyl, N-cycloalkyl, or N-aralkyl aziridines using a hydroxylamine amination agent with transition metal catalyst. The method is operationally simple (i.e., one-pot), scalable and fast at ambient temperature.
