碘化

Based on the comparison of the infrared spectra of polyamide homologues, on the changes in the infrared spectra of deuterated and iodine-treated samples of polycaprolactam, and also on the observations of the infrared dichroism of drawn film, the main absorption bands of polycaprolactam in the region 400 cm(-1)-1400cm-1, which are rather structure sensitive, have been assigned as follows: 1370 cm-1 band-VC-N;, 1265 cm-1 and 1205 cm-1 bands-; 1170 cm-1 band-VC-N; 730 cm-1 band-γCH2 of (CH2)n when n≥...

根据对聚酰胺类高聚物红外光谱的类比和对聚酰胺6试样进行氘化和碘处理后红外光谱的改变，以及根据对拉伸过的聚酰胺6薄膜试样的偏振红外光谱的观察，我们对聚酰胺6红外光谱中400cm~(-1)—1400cm~(-1)之间的主要吸收带，作了如下解释：1370cm~(-1)吸收带为ν_；1265cm~(-1)和1205cm~(-1)吸收带为δ_+ν_；1170cm~(-1)吸收带为ν_；730cm~(-1)吸收带为γ_(CH_2)[当(CH_2)_n的n≥4时]；690cm~(-1)吸收带为δ_；580cm~(-1)吸收带亦为δ_。

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〓。
