The layering of the reaction solution was caused by the immiscibility of DCPP-AlCl3 with the raw materials, greatly facilitating the dissociation process of DCPP-AlCl3. The formation of diphenylphosphorus chloride (DPC) was due to a continuous Friedel-Crafts reaction between DCPP and benzene. DPC ...
That is, the presence of AlCl3 efficiently promoted the Diels–Alder reaction to give a cycloadduct with high stereoselectivity, which was converted to an... MO Onomura - 《Tetrahedron Letters》 被引量: 179发表: 2000年 Alkylation of isobutane with 2-butene using ionic liquids as catalyst Alkyl...
The Friedel-Crafts reaction of phosphorus trichloride and benzene in [Et 4 N]Br-XAlCl 3 ([Et 4 N]Br = tetraethylammonium bromide) ionic liquids (ILs) was investigated for the clean synthesis of dichlorophenylphosphine (DCPP). A simple product isolation procedure was achieved, and the effects...
Benzoylacrylic acid was obtained by reacting maleic anhydride with benzene via Friedel-Crafts reaction, in the presence of anhydrous aluminum chloride. 顺丁烯二酸酐与苯在三氯化铝的存在下,经傅-克反应生成苯甲酰丙烯酸,在强酸性水介质中,若温度高于35℃,则部分发生与水的加成反应生成苯甲酰乳酸。 3. A...
In the case of the alkylation of benzene with ethylene, the reaction temperature generally ranges from 100 to 450° C. More specifically, with zeolitic catalysts, for either fixed or mobile bed processes in gas phase, the temperature preferably ranges from 300 to 450° C. or from 180 to ...
A reaction mechanism involving non-classical carbocation intermediates is proposed in order to account for the 5,7-enchainment of the bicycloheptenylene units, which contrasts with earlier studies on cationic norbornadiene polymerizations. Further, pentamethylbenzene was utilized as a chain transfer ...
