This material is available free of charge via the Internet at The Staudinger reactions of substituted phosphanes and azides have been investigated by using density functional theory. George C. Fortman, Burjor Captain and Carl D. Hoff. 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.
