Staudinger Reaction - Organic Chemistry Mechanism of the Staudinger Reaction. Triphenylphosphine reacts with the azide to generate a phosphazide, which loses N 2 to form an iminophosphorane. Aqueous work up leads to the amine and the very stable phosphine oxide. W. Q. Tian, Y. A. Wang, J. Org. Chem. 2004, 69, 4299.DOI Reaction Mechanism and Kinetics of the Traceless The traceless Staudinger ligation enables the formation of an amide bond between a phosphinothioester (or phosphinoester) and an azide without the incorporation of residual atoms. Here, the coupling of peptides by this reaction was characterized in detail. Experiments with [(18)O]H(2)O indicated tha … The traceless Staudinger ligation for indirect 18F The Staudinger ligation of phosphine-substituted thioesters with 18 F-fluoroethylazide has been successfully applied to access 18 F-labelled molecules in radiochemical yields superior to 95%; the first fluorous variant of a Staudinger radio-ligation has been validated.

Using this method, we uncovered the apoptotic effects of several ceramide species and observed differences in their apoptotic activity based on acyl-chain saturation. Additionally, we demonstrate spatiotemporally controlled ceramide synthesis in live cells through photoinitiated lipid ligation.
