A Practical One-Pot Transformation of Triphenylphosphine Oxide to Triphenylphosphine by Reduction of in situ Generated Triphenylphosphine Dichloride

摘要

One-pot transformation of triphenylphosphine oxide to triphenylphosphine was achieved by the reaction of triphenylphosphine oxide with oxalyl chloride, which led to the formation of triphenylphosphine dichloride, and subsequent reduction of triphenylphosphine dichloride with a combination of aluminum-catalytic metal salt.
