14221-01-3. Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.Tetrakis(triphenylphosphine)palladium, cas is 14221-01-3, below Introduce a new synthetic route.

Into a 20 mL brown Schlenk tube were placed Pd(PPh3)4(0.05 mmol, 0.0578 g), PdCl2(MeCN)2 (0.05 mmol, 0.0130 g), norbornene(2.1 mmol, 0.2 g), and K2CO3 (2.0 mmol, 0.277 g). Then, 4-iodotoluene (2.0 mmol, 0.26 mL) as well as 8 mL DMA (containing 0.5 M H2O) were transferred to the tube by syringe under N2. The mixturewas stirred at 70 C for 20 h. The solutionwas washed withH2O and ether. The organic layer was extracted twice with ether. It was then purified by Centrifugal Thin Layer Chromatography (CTLC)using CH2Cl2 as eluent. The solvent was removed under reduced pressure. The yield of 5a is 98% (0.0848 g, 0.0980 mmol). The residue was subjected to crystallization process by CH2Cl2 and hexanesand yellow crystals were resulted. Similar processes were taken forthe preparation of 5b except that dicyclopentadiene (2.0 mmol,0.264 g) was used. The yield of 5b is 98% (0.0922 g, 0.0980 mmol). Yellow crystals were resulted in crystallization process by CH2Cl2and heptane.

In every case, we must determine the overall rate law from experimental data and deduce the mechanism from the rate law (and sometimes from other data). you can also browse my other articles about 14221-01-3 if you are interested.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials.14221-01-3,A new synthetic method of this compound is introduced below.14221-01-3
