Hexamethyldisilazane is used as a solvent in organic synthesis and organometallic chemistry. It is often used as an adhesion promoter for photoresist in photolithography. Further, it is used for the preparation of trimethylsilyl ethers from hydroxy compounds. It is used as an alternative to critical point drying during sample preparation in electron microscopy. It is added to analyte to get silylated diagnostic products during pyrolysis in gas chromatography- mass spectrometry.
Tri-m-tolylphosphine serves as a sterically hindered, bench-stable phosphine ligand that facilitates cross-coupling reactions in palladium-catalyzed processes. Its three meta-tolyl groups provide enhanced oxidative stability and improved solubility in organic media, enabling efficient catalysis in Suzuki-Miyaura, Stille, and Negishi couplings. The ligand exhibits excellent functional group tolerance and simplifies purification due to its low volatility and resistance to air oxidation.
