Cesium and water, and even and low temperature to - 116 degrees of ice can occur with violent reaction, also can generate stable halogen halide, this is because it is caused by large radius of ions.
铯和水,甚至和温度低到-116℃的冰均可发生猛烈反应,与卤素也可生成稳定的卤化物,这是由于它的离子半径大所带来的特点。

According to the H NMRstudy, it was found that the protons on the cyclopentadienyl ring of 〓 were not splitted, but when one proton on the cyclopentadienylring was substituted by methyl, that is in〓 complexes, thefour protons on the ring were splitted into four groups,the 〓 between the onesignal and the others is large, the total splitting is over 2ppm. The splittings werealso affected by the halides linked with the titanium, they increase according to theorder of CI, Br, I. By the study of the 〓 Sn NMR, it is found that the chemicalshifts of 〓 are present in low field. It is assume that the large space strain causesthe angles of the tin linked with ligands deviate from the normal tetrahedral anglesresults low field shift for 〓Sn. And by MS study,there were no molecular ions for 〓 complexes in the spectra. However, for 〓 when X=CI,Br,NCO and Ar is tolyl or phenyl group,there were molecular ions,but theirabundances were very small,and no that for the iodide was found.
钛上的卤素对茂环氢的裂分也有影响,依〓,Br,I顺序,卤素对茂环氢的裂分依次加大;通过对〓的研究发现,以上这些化合物〓的化学位移都出现在低场,认为大的空间张力造成的锡的键角偏离正常的锡的四面体键角是造成〓化学位移出现在低场的原因;对这些化合物质谱的研究发现,〓系列化合物得不到分子离子峰,而〓系列的化合物,当X=〓,NCO和苯环上不带取代基或只带甲基时,则出现分子离子峰,但丰度很低,而相应的碘化物和其它化合物则没出现分子离子峰。

halide:卤化物
大部分免清洗焊剂都不含卤化物(halide),因陋就简其活化能力较传统的焊剂低,在这情况下,使用速度较慢的输送带(1.2m/s至1.8/s)较为理想. 焊锡温度及焊锅活动免清洗剂的美妙之处,是其活化剂可在高温下完全分解,之后亦不会留下腐蚀性残渣.
