A new type of molybdenum alkylidyne catalysts for alkynemetathesis is described, which is distinguished by an unconventional podand topology. These structurally well-definedcomplexes are easy to make on scale and proved to be tolerant toward numerous functional groups; even certain protic substituents were found to be compatible. The new catalysts were characterized by X-ray crystallography and by
描述了一种用于炔复分解的新型钼亚烷基催化剂,其特点是非常规的荚状拓扑结构。这些结构明确的复合物很容易大规模制造,并且被证明对多种官能团具有耐受性;甚至发现某些质子取代基是相容的。新催化剂通过 X 射线晶体学和光谱手段(包括 95 Mo NMR)进行了表征。
