It also serves as an alternative way to navigate the website, and as a means of coming up with retrosynthetic ideas. Emandi Ganapathi, Sheri Madhu, Tamal Chatterjee, Rajesh Gonnade, Mangalampalli Ravikanth. The reaction between an azide and triphenylphosphine (or phosphonite) to produce an iminophosphorane (the nucleophilic aza‐ylide) and subsequent hydrolysis to yield a primary amine is generally known as the Staudinger reaction. In contrast to the previous predictions on the relative stability of the unsubstituted cis-configured phosphazide intermediate and the unsubstituted trans-configured phosphazide intermediate, the total energy of the substituted trans-configured phosphazide intermediate is close to that of the substituted cis-configured phosphazide intermediate.

The reaction between an azide and triphenylphosphine (or phosphonite) to produce an iminophosphorane (the nucleophilic aza‐ylide) and subsequent hydrolysis to yield a primary amine is generally known as the Staudinger reaction.This reaction is a specific, high‐yielding reaction in which the iminophosphorane intermediate hydrolyzes spontaneously in the presence of water.
