1)  aryl iodides
碘代芳烃
1.
Although a few examples on the cross-couplings between two different aryl halides have been disclosed, the catalytic cross-couplings of only aryl iodides are rarely reported because enhancing the reaction selectivity on the formation of unsymmetrical products is not easy using the current systems.
虽然有关不同的卤代芳烃之间,如碘代芳烃和溴代芳烃、溴代芳烃和氯代芳烃等,实现交叉偶联已有报导,但是仅在碘代芳烃之间实现交叉偶联反应的研究成果,还非常少见。
2)  alkyl iodides
碘代烷烃
1.
Multiphoton Ionization-Dissociation (MPID) Mass Spectra (MS) of alkyl iodides (including methyl iodide, ethyl iodide, n-propyl iodide and i-propyl iodide) are obtained using a time-of-flight mass spectrometer at 532 nm.
利用532nm的激光对碘代烷烃(碘甲烷,碘乙烷,碘代正丙烷,碘代异丙烷)分子作了多光子电离解离(MPID)质谱(MS)研究。
3)  aliphatic iodocompounds
碘代烯烃
4)  aliphatic iodocompounds
碘代烃
5)  aryl bromide
溴代芳烃
1.
Suzuki cross-coupling reactions between aryl bromides and phenylboronic acids were studied over a hydroxyapatite-supported Mn catalyst(MnHAP) for the first time.
对于不同取代基取代的溴代芳烃或苯硼酸,可以得到中等产率(18%~46%)的偶联产物。
2.
The palladium catalyst supported on fluoride pillared layered double hydroxide(LDH-F) was prepared by the incipient wetness method,and it was used to catalyze the Heck and Suzuki coupling reactions of aryl bromides.
以氟离子插层的水滑石LDH-F为载体,用逐滴浸渍法制备了新型Pd/LDH-F催化剂,并用其催化溴代芳烃的Heck和Suzuki偶联反应。
6)  aryl halide
卤代芳烃
1.
Ligand free Ullmann coupling reactions of aryl halides catalyzed by Pd/C were studied in O/W Triton X10 microemulsion(ME) in comparison with biphase systems.

补充资料:碘代芳烃
分子式:
CAS号:

性质:代表脂肪族化合物分子中的氢原子被碘元素取代后生成的化合物。常指碘代脂肪烃与碘代芳烃,合称为碘代烃。碘代脂脂烃主要又分为碘代烷(简称碘烷)和碘代烯烃。常见一元碘烷烃为液体,因易分解而呈红棕色。其沸点随碳原子数增加而升高。在同一烃基的卤烷中,以碘烷的沸点和比重最高。在碘烷的同分异构体中,支链增多,沸点降低。碘烷不溶于水,溶于醇、醚、烃等有机溶剂。碘的有机化合物比相应结构溴代卤代化合物有低的生成热,高的反应活性。碘烷不存在于自然界,常用的合成方法有在氧化剂存在下的碘代反应,不饱和烃和碘化氢加成,卤素的置换反应,还可通过醇羟基被碘原子取代的方法制备。
