1271-51-8, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Vinylferrocene, cas is 1271-51-8,the iron-catalyst compound, it is a common compound, a new synthetic route is introduced below.
General procedure: 25mL reaction flask, weighing 2molpercent palladium acetate and 4molpercent ferrocenylpyrimidine multidentate ligand 6h, adding 12 water, stirring for 5min, 4 mmol of p-nitrochlorobenzene, 4.8 mmol of butyl acrylate, 6 mmol of potassium phosphate, and 0.8 mmol of tetrabutylammonium bromide were added successively. The reaction was heated to 80¡ãC until the reaction was complete (the reaction did not continue after about 6 h, and palladium black appeared in the reaction flask). After adding 25 mL of ethyl acetate and washing three times with water, the organic phases were combined, dried over anhydrous sodium sulfate, concentrated, and the residue was separated by column chromatography. PE/EA=12:1 was used as an eluent to obtain 707 mg of a yellow solid with a yield of 71percent.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Vinylferrocene, 1271-51-8
