摘要：

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(mu-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.
