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.
Copper(II) acetate/oxygen-mediated nucleophilic addition and intramolecular C-H activation/C-N or C-C bond formation: One-pot synthesis of benzimidazoles or quinazolines
He, Hua-Feng,Wang, Zhi-Jing,Bao, Weiliang
supporting information; experimental part, p. 2905 - 2912 (2010/12/29)
Diarylcarbodiimides or benzylphenylcarbodiimides are converted to 1,2-disubstituted benzimidazoles or 1,2-disustituted quinazolines via addition/intramolecular C-H bond activation/C-N or C-C bond forming reaction using copper(II) acetate/oxygen [Cu(OAc)2/O2] as the oxidant at 100°C in one-pot cascade procedure.

Crystalline phosphorus ylides are obtained in excellent yields from the 1:1:1 addition reaction between triphenylphosphine, dimethyl acetylenedicarboxylate and aromatic amines, such as aniline, 1-naphthylamine, p-toluidine, 4-bromoaniline, 4-nitroaniline, 4-acetylaniline, 2-aminopyridine, or 2-amino-5-bromopyridine. These stabilized phosphoranes undergo a smooth intramolecular reaction in boiling p-xylene or toluene to produce aryliminophosphoranes in excellent yields.
Iminophosphorane-substituted Proton Sponges. Part 2. Preparation and Crystal Structure of Four Phosphoranylideneammonionaphthalene Derivatives
Llamas-Saiz, Antonio L.,Foces-Foces, Concepcion,Elguero, Jose,Molina, Pedro,Alajarin, Mateo,Vidal, Angel
, p. 1667 - 1676 (2007/10/02)
Crystal structure analysis of salts of one monosubstituted (1) and three peri disubstituted naphthalene derivatives (2, 3 and 4) are described.The strong repulsion between the nitrogen lone pairs in neutral structures is replaced by an intramolecular N(1+
