| Research Abstract |
We found that, with regard to the complexes having a double or triple bond between tungsten or ruthenium and silicon or germanium, reduction of the steric hindrance of substituents caused the dramatic enhancement of reactivity of the metal-Group 14 element unsaturated bond, and their reactions with various organic molecules proceeded smoothly. Especially, we clarified the reactivity of the tungsten-germanium triple bond toward organic molecules for the first time. We also demonstrated that η^3-α-silabenzyl tungsten and molybdenum complexes serve as the synthetic equivalents of both silylene complexes and coordinatively unsaturated complexes.
