Three-component reaction of triphenylphosphine, dialkyl acetylenedicarboxylates, and heterocyclic rings and the related iminophosphoranes
Anary-Abbasinejad, Mohammad,Hassanabadi, Alireza,Khaksari, Zahra
, p. 204 - 212 (2011/10/31)
Crystalline phosphorus ylides are obtained in excellent yields from the 1:1:1 addition reaction of triphenylphosphine, dialkyl acetylenedicarboxylate, and NH acids, such as 2-aminothiazole and 2-aminobenzothiazole. These stabilized phosphoranes undergo a
Reaction between triphenylphosphine and aromatic amines in the presence of diethyl azodicarboxylate: An efficient synthesis of aryliminophosphoranes under neutral and mild conditions
Adib, Mehdi,Sheikhi, Ehsan,Deljoush, Azadeh
experimental part, p. 4137 - 4140 (2011/06/24)
An efficient synthesis of aryliminophosphoranes is described. A mixture of an aromatic amine, diethyl azodicarboxylate and triphenylphosphine undergo a Mitsonobu type reaction at ambient temperature in dry dichloromethane to afford aryliminophosphoranes in excellent yields.
Vinyltriphenylphosphonium salt-mediated efficient synthesis of iminophosphoranes derived from 2-aminothiazoles

Crystalline phosphorus ylides are obtained in excellent yields from the 1:1:1 addition reaction between triphenylphosphine, dimethyl acetylenedicarboxylate and 2-aminothiazoles, such as 2-aminothiazole, 2-amino-3-methylthiazole, 2-aminothiazoline, 2-aminobenzothiazole, or 2-amino-7-methylbenzothiazole. These stabilized phosphoranes undergo a smooth intramolecular reaction in boiling toluene to produce the corresponding iminophosphoranes in excellent yields. Georg Thieme Verlag Stuttgart.
