Triphenyl oxide

WebTriphenylphosphine mediates a metal-free, intermolecular, reductive amination between nitroarenes and boronic acids at ambient temperature under visible-light irradiation without any photocatalyst. A wide range of nitroarenes underwent C-N coupling with aryl-/alkylboronic acids providing high yields. WebNov 4, 2006 · The solubility of triphenylphosphine in ethanol was compared with the literature data and agreed with the literature data within 1.7 %. Although ethanol is often used for recrystallization of triphenylphosphine, the solubility of triphenylphosphine in acetone was higher compared with other solvents.
