Unless otherwise stated, all reagents and solvents were purchased from commercial suppliers and used without further purification. Cu(0) wire (diameter: 0.25 mm, purity 99.9%) was purchased from Sigma-Aldrich. Me6TREN was purchased from Alfa Aesar. Compounds 2a 5a and 12 11 were prepared according to literature procedures. Gel permeation chromatography (GPC) analyses were performed in THF solution (~0.6 mg mL General procedure for the synthesis of 3,3-diarylacrylates 2 A solution of 1 (2 mmol, 1.0 eq.) and methyl (triphenylphosphoranylidene) acetate (2.4 mmol, 1.2 eq.) in toluene (5 mL) was heated to reflux for 36 h in an oil bath. The solvent was removed and the crude product was purified by flash column chromatography (PE : EtOAc = 10:1) to give 2.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
