Description

Platinum, tetrakis(triphenylphosphine)-, (T-4)- (CAS No. 14221-02-4) is a highly specialized organometallic compound with the molecular formula C₇₂H₆₀P₄Pt. This platinum(0) complex features four triphenylphosphine (PPh₃) ligands coordinated to a central platinum atom, forming a tetrahedral geometry. It is a valuable catalyst in organic synthesis, particularly for hydrogenation, hydrosilylation, and cross-coupling reactions. The compound is supplied as a yellow to orange crystalline powder, soluble in organic solvents such as toluene and dichloromethane but insoluble in water. With a purity of ≥97%, it is ideal for research and industrial applications requiring precise catalytic activity. Store under inert conditions (argon or nitrogen) to prevent oxidation and degradation.

This platinum complex is widely used as a homogeneous catalyst in organic transformations, including hydrogenation of alkenes and alkynes, hydrosilylation reactions, and C-C bond-forming processes like the Stille coupling. Its electron-rich nature and stability make it suitable for mechanistic studies in organometallic chemistry. Researchers also employ it in the synthesis of fine chemicals and pharmaceutical intermediates due to its high selectivity and efficiency.
