摘要

琴凳复合物(C5Me5)- time3,1与HSCPh3反应生成(C5Me5)-TiMe2(SCPh3), 2。用碱金属（K或Na）还原2生成[K-（隐窝）]-[(C5Me5)- time2 (S)], 3-K-（隐窝）和(C5Me5)- time2 (μ-S)-M-(18-crown-6), 3-M-(18c6) （M = K, Na）硫化物配合物。3-K-（隐窝）是钢琴凳钛复合物的第一个例子，具有终端硫化物。化合物1-3是光敏的，通过光解实验，通过1H NMR和紫外可见光谱监测，表明1是最光稳定的，3是最不光稳定的。

Synthesis, Characterization, and Light Sensitivity in Titanium Piano Stool Alkyl and Sulfur Complexes, [(C₅Me₅)TiMe₂R] ^n- (R = Me, SCPh₃, S; n = 0, 1).

The piano stool complex (C₅Me₅)-TiMe₃, 1, reacts with HSCPh₃ to produce (C₅Me₅)-TiMe₂(SCPh₃), 2. Reduction of 2 with an alkali metal (K or Na) produces the sulfide complexes [K-(crypt)]-[(C₅Me₅)-TiMe₂(S)], 3-K-(crypt), and (C₅Me₅)-TiMe₂(μ-S)-M-(18-crown-6), 3-M-(18c6) (M = K, Na). 3-K-(crypt) is the first example of a piano stool titanium complex featuring a terminal sulfide. Compounds 1-3 are photosensitive, with photolysis experiments, monitored through ¹H NMR and UV-visible spectroscopies, demonstrating 1 as the most photostable and 3 as the least photostable.

期刊介绍： Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
