- 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.

- Reaction between triphenylphosphine and aromatic amines in the presence of diethyl azodicarboxylate: An efficient synthesis of aryliminophosphoranes under neutral and mild conditions
-
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.
