Methods IO(superscript - subscript 3) was prepared by quantitative oxidation of bromine water, with the excessive bromine removed with formic acid. In the presence of excessive iodide, I(superscript -) would be oxidized by I(superscript - subscript 3) to form 3 times of I(superscript - subscript 3) in mol, displaying maximal absorption at 286nm in ultraviolet zone and a slightly low apex at 345nm.ε286=1.3×10^5 Lmol^(-1)cm^(-1),ε345=8.1×10^4 Lmol^(-1)cm^(-1), with both showing high sensitivity.

Monophenyltin trichloride reacts withdicarbonyl dicyclopentadienyl titanium immediately at room temperature, but no ti-tanium-tin complex produced, and the products were diphenyltin dichloride〓 and tin or stannous Chloride. When diaryltin dihalides were used, only the chlorides and bromides reacted with 〓form the complexes containing titaninm-tin bond,〓. but the corresponding iodide complex was not found. This reaction is Sensitive totemperature,when the temperature is belw 10℃,the reaction hardly takes place,but as the temperature is above 25℃,more 〓 will be found and the reactionbecome more complex.
Ph-SnC〓室温下即可与Cp〓迅速反应,但不生成含钛一锡链的化合物,而是生成Ph〓和Sn或Sn〓二芳基二卤化锡化物中,只有氯化物和溴化物才能和〓反应生成含钛〓锡键的化合物〓相应的碘化物则不行,而且反应对温度比较敏感,低于10℃,反应几乎不能进行,而高于25〓,则会生成更多的〓,在回流条件下得不到含钛〓锡键的化合物,只能得到分解产物,〓和Sn或〓。
