Usage

General Description

(2,4,6-Tri-tert-butylphenyl)phosphine, also known as TTBPP, is a phosphine compound with the molecular formula C27H39P. It is frequently used as a ligand in organometallic chemistry, particularly in catalytic reactions and transition metal complexes. TTBPP is a sterically bulky phosphine ligand, which makes it useful in promoting selective reactions and stabilizing metal complexes. Its tert-butyl groups provide steric protection and can influence the reactivity and selectivity of the metal center in a catalytic system. TTBPP has also been employed in the development of novel catalytic processes, including the synthesis of pharmaceuticals and fine chemicals. Additionally, this compound has been studied for its potential applications in materials science and as a stabilizer for metal nanoparticles.

Dichloro-Cycloazatriphosphane: The Missing Link between N2P2 and P4 Ring Systems in the Systematic Development of NP Chemistry

A dichloro-cycloazatriphosphane that incorporates a cyclic NP3 backbone could be synthesized using knowledge gained from the chemistry of N2P2 and P4 ring systems. It fills the gap between the congeneric compounds [ClP(μ-NR)]2 and [ClP(μ-PR)]2 (R=sterically demanding substituent), and thus contributes to the systematic development of nitrogen–phosphorus chemistry in general. The title compound was studied with respect to its formation via a labile aminodiphosphene, which readily underwent different rearrangement reactions depending on the solvent. All compounds were fully characterized by experimental and computational methods.
