Reaction conditions varied according to the nature of the ylide and the method by which it was generated. Staudinger's reaction remained, with rare exceptions < 69JA6112, 70JOC862 >, almost entirely unexplored until Frøyen used it for preparing a range of ketenimines from various isocyanates (Table 8) < 74ACS(B)586 >. This reaction has been applied in organic synthesis, especially in the preparation of peptide bonds in a living system. Your Mendeley pairing has expired.

Traceless Staudinger Ligation of Glycosyl Azides with Triaryl Phosphines:  Stereoselective Synthesis of Glycosyl Amides. Rebecca L. Melen, Alan J. Lough, Douglas W. Stephan. Recent progress on the stereoselective synthesis of cyclic quaternary α-amino acids. Depending on the substituents on the azide and the phosphane, the reaction mechanism with the lowest initial reaction barrier can be classified into three categories:  (1) like the parent reaction, PH3 + N3H, the reaction goes through a cis-transition state, approaches a cis-intermediate, overcomes a PN-bond-shifting transition state, reaches a four-membered ring intermediate, dissociates N2 by overcoming a small barrier, and results in the final products:  N2 and a phosphazene; (2) once reaching the cis-intermediate, the reaction goes through the N2-eliminating transition state and produces the final products; (3) the reaction has a concerted initial cis-transition state, in which the phosphorus atom attacks the first and the third nitrogen atoms of the azide simultaneously and reaches an intermediate, and then the reaction goes through similar steps of the first reaction mechanism.
