This International Collaborations in Chemistry award funded by the Inorganic, Bioinorganic, and Organometallic Chemistry Program and the Office of International Science and Engineering supports work by Professor Guy Bertrand of the University of California at Riverside to carry out fundamental/basic studies on the use of stable carbenes. These novel carbenes are used for stabilizing highly reactive species and for activating stable molecules. The synthesis of carbene-stabilized monoatomic and diatomic carbon(0) compounds is being investigated. These compounds are of considerable importance in biology and in synthetic chemistry. Synthetic cycles using carbenes to activate P4 and the subsequent addition of organic fragments to the ensuing highly reactive mono- and diatomic phosphorus species are being developed. Indeed, processes using white phosphorus, but avoiding chlorine, are highly desirable to meet the growing demand for phosphorus derivatives under increasingly stringent environmental regulations. The carbene-induced de-oligomerization of BNH containing polymers also under investigation. The greatest technical barrier for a practical application of ammonia borane as a hydrogen-storage material for fuel-cell-powered vehicles lies in the discovery of energy-efficient regeneration routes from the polymers that are formed in the dehydrogenation process. Calculations to accurately describe these novel compounds are being performed by Professor Bertrand's German collaborator, Professor Gernot Frenking of Phillipps-Universitaet Marburg. This German work is separatately supported by the Deutsche Forschungsgemeinschaft (DFG). This project is at the interfaces between organic, inorganic, and physical chemistry and is well-suited for the multidisciplinary education of graduate coworkers. The graduate students of the U.S. and German groups involved in this collaborative effort have the opportunity to learn both computational and experimental techniques through reciprocal visits of three months. This project addresses several issues that are of critical importance for society, such as the study of substances with potential biological applications (para-benzynes), the environmentally friendly synthesis of bulk chemicals (phosphorus derivatives), and the hydrogen economy (ammoniaborane).

这项由无机，生物无机和有机金属化学计划和国际科学与工程办公室资助的化学合作奖和加利福尼亚大学河滨大学盖伊·贝特兰德教授的工作提供了有关稳定碳烯使用的基本/基础研究的工作。 这些新型的碳烯用于稳定高反应性物种和激活稳定分子。 正在研究Carbene稳定的单原子和双原子碳（0）化合物的合成。 这些化合物在生物学和合成化学中至关重要。 使用碳烯激活P4的合成循环，并在随后在随后的高反应性单磷和硅藻磷中添加有机片段。 实际上，使用白磷但避免氯的过程非常需要满足日益严格的环境法规对磷衍生物的不断增长的需求。 卡宾诱导的含有BNH的聚合物的去寡聚化也正在研究中。 将氨基氨基氨水作为燃料电池驱动车辆的氢存储材料实际应用的最大技术障碍在于发现从脱氢过程中形成的聚合物中发现节能的再生途径。 精确描述这些新颖化合物的计算是由贝特兰教授的德国合作者，菲利普斯 - 诺弗斯伊弗斯塔特·马尔伯格的Gernot Frenking教授进行的。这项德国作品由德意志Forschungsgemeinschaft（DFG）分开支持。 该项目位于有机，无机和物理化学之间的界面，非常适合研究生同事的多学科教育。参与这项合作努力的美国和德国团体的研究生有机会通过三个月的相互访问来学习计算和实验技术。该项目解决了对社会至关重要的几个问题，例如研究具有潜在生物应用的物质（Para-Benzynes），对散装化学物质（磷衍生物）的环境友好合成和氢经济（Ammoniaiaborane）。
