U.S.-Latin America Cooperative Research: Micellar and Metal-Ion Interactions with Terpenoid and Sugar Derivatives

发展中国家科学奖支持由加州大学圣巴巴拉分校的克利福德·邦顿和圣地亚哥智利大学的塞尔吉奥·布内尔及其同事在反应化学动力学方面进行的合作研究。他们将研究二价金属离子，特别是与这些金属离子强烈相互作用的离子表面活性剂催化的萜类磷酸盐的反应。将研究叠氮离子的重排和热分解，以及糖与过渡金属的络合物。叠氮离子用于捕获萜类酯和卤化物的水解中间体。包括标记化合物在内的准备工作将在智利大学布内尔的实验室进行。各种分析，如高场核磁共振，傅里叶变换红外光谱和气质联用，将在圣巴巴拉进行。动力学研究将在两个中心进行。因此，这两个实验室的优势有助于国际合作产生的科学。

This Science in Developing Countries award supports cooperative research in the kinetics of reaction chemistry to be conducted by Clifford Bunton of the University of California at Santa Barbara and Sergio Bunel and colleagues of the University of Chile in Santiago. They will study reactions of terpenoid phosphates catalyzed by bivalent metal ions, especially ionic surfactants that interact strongly with these metal cations. Rearrangements and thermal decompositions of azide ions, used to trap intermediates in hydrolysis of terpenoid esters and halides, will be examined as will sugar complexes with transition metals. The preparation work including that with labelled compounds will be done in Bunel's laboratory at the University of Chile. Various analyses, such as high field NMR, Fourier Transform Infrared spectroscopy and GLC mass spectrometry will be done in Santa Barbara. Kinetic studies will be performed at both centers. Thus the strengths of the two laboratories contribute to the science produced by international cooperation.
