Catalytic Staudinger Reduction at Room Temperature [PDF]

The Journal of Organic Chemistry, 2019
We report an efficient catalytic Staudinger reduction at room temperature that enables the preparation of a structurally diverse set of amines from azides in excellent yields. The reaction is based on the use of catalytic amounts of triphenylphosphine as a phosphine source and diphenyldisiloxane as a reducing agent.
