[5] In aqueous media, the aza-ylide intermediate rearranges, to produce an amide linkage and the phosphine oxide, and is so named the Staudinger ligation because it ligates two molecules together, whereas in the classical Staudinger reaction, the two products are not covalently linked after hydrolysis. doi:10.1002/cjoc.200690157.

Bioorg Med Chem Lett 15:4247–4251. The azide group is usually reduced to the amino function by catalytic reduction (using Raney nickel, palladium, etc) or by treatment with lithium aluminium hydride. We have found that the yields of the amine obtained by catalytic hydrogenation are, in some cases, low or variable, and the products are difficult to purify'.

Of interest in chemical biology research, the Staudinger ligation is a modification of the classical Staudinger reaction in which an electrophilic trap (usually a methyl ester) is placed on the triaryl phosphine. Acc Chem Res 35:887–894. The intermediate, e.g. The reaction mechanism centers around the formation of an iminophosphorane through nucleophilic addition of the aryl or alkyl phosphine at the terminal nitrogen atom of the organic azide and expulsion of diatomic nitrogen. [6], In one application this reaction is used to create a bond between a nucleoside and a fluorescent marker:[7][8], The Staudinger ligation is used to site-specifically incorporate organic molecules (such as fluorescent dyes) into recombinant polypeptides containing unnatural azide-conjugated aminoacids (incorporated, for instance, via suppression of the amber stop codon:, For the reaction between imines and ketenes to form,, "Über neue organische Phosphorverbindungen III.
