The reason may be that complex formed by rhodium and halide was difficult to produce the catalytic active species. Therefore halide ion was the poison for the rhodium catalyst in hydroformylation of olefins in ionic liquid. The effect of double long chain cationic surfactant (DCMAB, dicetyl dimethylammonium bromide) on selective hydrogenation of cinnmaldehyde catalyzed with RuCl3·x H2O/TPPTS was studied.

进一步的研究表明在使用有良好反应活性的两种催化剂HRh3 、Rh_2进行催化反应时，向体系中加入含有卤离子的化合物时将使反应活性大大降低，而且随着卤化物加入量的增加，催化剂的活性迅速下降，这是卤离子可能和金属铑作用使它难于生成催化活性物种，进一步证明卤素离子是引起催化剂活性下降的极其重要的因素。

At first it may seem rather strange to treat the chemistry of the halogens and the noble gases,two groups that represent the extremes of chemical activity and inertia ,in the same section .the superficial differences between the halogens and the noble gases are much reduced,however if we focus our attention on the comparison of halide ions(particularly F-) with the isoelectronic noble gas atoms and the noble gas compounds with halogen atoms or the halogens in their higher positive-oxdation states.

起初它可能看起来很奇怪对待的卤素化学和惰性气体，两个团体代表在同一节的化学活性和惯性的极端。与卤素和惰性气体的表面差异大大减少，但是，如果我们着眼于（特别是架F -等电子与惰性气体原子和原子与卤素或在卤素稀有气体化合物）卤离子的比较，我们的注意力较高的正- oxdation国家。

The binding of different halide anions to four strapped calix[4]pyrroles was studied by means of molecular mechanics and molecular dynamics simulations methods. The results indicate that the anion binding ability of calix[4]pyrrole-type systems could be effectively tuned by modifying the length and nature of the bridging straps. In this process, it was the most stable conformation upon anion binding due to the formation of four NH\|halide hydrogen bond, simultaneity, the difference of cavity by modifying straps adapted themselves to different halide anion.

模拟结果表明，加入带状修饰链和调节链长可以增强对某种特殊卤素阴离子的识别，在这个过程中，卤素阴离子与杯[4]吡咯NH上的氢形成的多氢键使主体分子与阴离子形成稳定复合物，同时带状修饰链通过改变杯吡咯空腔大小影响主体分子与卤素阴离子的氢键相互作用，从而调节了对不同阴离子的识别能力。
