General Description

1H,1H,2H,2H-perfluorodecyldimethylchlorosilane is a chemical compound with the molecular formula C12H25ClF17Si. It is a perfluorinated alkylsilane, which means it contains a fluorinated alkyl group attached to a silicon atom. 1H,1H,2H,2H-PERFLUORODECYLDIMETHYLCHLOROSILANE is commonly used as a surface modifier in various industrial applications, such as in the production of water and oil resistant coatings, adhesives, and sealants. It provides excellent water and oil repellent properties due to its highly fluorinated alkyl chain. Additionally, it can be used as a coupling agent in the synthesis of fluorinated polymers and as a surface modifier for various materials, including glass, metals, and plastics. It is important to handle this chemical with caution, as it may be harmful if swallowed or inhaled and can cause skin and eye irritation upon contact.

Synthesis and properties of a novel family of fluorous triphenylphosphine derivatives

A novel approach to the preparation of perfluorotail-functionalized triarylphosphines using a p-silyl substituent as the branching point has been developed. This approach enabled the attachment of between three and nine perfluorotails per phosphorus atom, resulting in the production of highly fluorous tris[p-(1H,1H,2H,2H-perfluoroalkylsilyl)aryl]phosphines, P[C6H4-p-SiMe3-n(CH2 CH2CxF2x+1)n]3 (n = 1, 2, 3; x = 6, 8), containing between 50 and 67 wt % fluorine. 31P NMR studies indicate that the phosphorus atoms, and consequently the σ-donor and π-acceptor properties of these phosphines, are not influenced by the electron-withdrawing perfluoroalkyltails. The fluorous triarylphosphines are readily soluble in fluorous solvents and display fluorous phase preference in several fluorous biphasic systems. The phase partitioning of these fluorous ligands, as well as their donor properties, is discussed in relation to their potential for fluorous biphasic catalyst separation.
