Abstract

The piano stool complex (CMe)-TiMe, , reacts with HSCPh to produce (CMe)-TiMe(SCPh), . Reduction of with an alkali metal (K or Na) produces the sulfide complexes [K-(crypt)]-[(CMe)-TiMe(S)], , and (CMe)-TiMe(μ-S)-M-(18-crown-6), (M = K, Na). is the first example of a piano stool titanium complex featuring a terminal sulfide. Compounds are photosensitive, with photolysis experiments, monitored through H NMR and UV-visible spectroscopies, demonstrating as the most photostable and as the least photostable.

摘要

钢琴凳配合物（CMe）-TiMe与HSCPh反应生成（CMe）-TiMe（SCPh）。用碱金属（K或Na）还原得到硫化物配合物[K-（穴醚）]-[(CMe)-TiMe(S)]以及（CMe）-TiMe（μ-S）-M-（18-冠-6）（M = K，Na）。是具有端基硫化物的钢琴凳钛配合物的首个实例。化合物对光敏感，通过核磁共振氢谱和紫外可见光谱监测的光解实验表明是最光稳定的，而是最不光稳定的。
