This award in the Chemical Synthesis (SYN) program supports work by Professor T. Don Tilley at the University of California, Berkeley, to carry out fundamental studies on the search for new chemical transformations that are mediated by transition metal-main group element multiple bonds. In general, reactivity centered on multiple metal-ligand bonds is very important, and the chemistry of metal-silicon double bonds in silylene complexes is expected to lead to new, useful transformations. Chemical conversions mediated by silylene complexes have recently been found to promote the addition of hydrogen-silicon bonds to alkenes, and a range of related transformations seem likely. The fundamental principles established from these studies should be applicable to a range of problems in chemistry, materials science and catalysis. The basic research of this proposal should point the way to replacement of rare and expensive metals such as platinum and rhodium with less abundant metals such as iron and cobalt, in industrial catalytic processes. In general, new, more efficient chemical transformations will enable the more efficient use of energy and resources.

化学合成（SYN）计划的这一奖项支持了T。唐蒂利在加州大学伯克利分校，进行基础研究，寻找新的化学转化，是由过渡金属主族元素多重键介导。一般来说，以多个金属-配体键为中心的反应性是非常重要的，并且亚甲硅烷基络合物中的金属-硅双键的化学有望导致新的有用的转化。最近发现由硅烯络合物介导的化学转化促进氢-硅键加成到烯烃上，并且一系列相关的转化似乎是可能的。从这些研究中建立的基本原则应该适用于化学，材料科学和催化中的一系列问题。该提案的基础研究应指明在工业催化过程中用铁和钴等不太丰富的金属取代铂和铑等稀有和昂贵的金属的方法。总的来说，新的、更有效的化学转化将使能源和资源得到更有效的利用。
