In heterogeneous catalysis, the catalyst is in a different phase from the reactants. SDS of cas: 95464-05-4, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 95464-05-4, name is 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex. In an article£¬Which mentioned a new discovery about 95464-05-4
A 3-aryl-2-cyclopenten-1-one compound method for the synthesis of (by machine translation)
The invention relates to a kind of the following formula (III) shown in the 3 […] aryl -2 the […] cyclopentene -1 the method for synthesizing compound of […], the method comprising: under a nitrogen atmosphere, in an organic solvent, the catalyst, in the presence of alkali and, the following formula (I) compounds and the following formula (II) compound in 40 the […] 50 C reaction under the 1 […] 2 hours, then raise the temperature, in the 70 […] 80 C reaction under the 4 […] 6 hours, so as to obtain the compound of said formula (III), wherein R 1 to C 1 ? C 6 alkyl or C 1 ? C 6 alkoxythiophene; R 2 to C 1 ? C 6 alkyl or halogenated C 1 ? C 6 alkyl; X is or S N; n is 1 or 2. The stated method, through catalyst, alkali, organic solvent, etc. of the auxiliary agent and combined and synergies, and through the control of reaction temperature, thus the objective product may be obtained in a high yield, in the field of organic synthesis technology has good prospects and research potential application of.
