1,1',1''-phosphinoylidynetripiperidine synthesis

Yield:-

Reaction Conditions:

with trichlorophosphate in acetonitrile at -0.16; for 4 h;

Steps:

2.1.1. Tripiperidinophosphine oxide, [C₅H₁₀N]₃PO

The ligand, [C₅H₁₀N]₃PO, was previously reported to form as a by-product in a reaction yielding {[C₅H₁₀N]₄P}Br [29]. Here, the synthesis of [C₅H₁₀N]₃PO was performed by a different method summarized by Eq. (1) and described as follows: a solution of piperidine (6 mmol) in dry acetonitrile (5 ml) was added dropwise to a solution of P(O)Cl₃ (1 mmol) in the same solvent (30 ml) at 273 K. After stirring for 4 h, the precipitated amine hydrochloride salt (C₅H₁₀NH.HCl) was filtered, and the acetonitrile solution of the ligand was used in the complex reaction.
