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.
