Understanding the fundamental chemical properties and synthesis pathways of specialized compounds is essential for their effective utilization in various industries. Silane, 1,3-Phenylenebis[triphenyl], also known as 1,3-Bis(triphenylsilyl)benzene, with CAS number 18920-16-6, is a complex organosilicon compound that garners interest for its unique characteristics.

The compound presents as a white powder, and its thermal stability is indicated by a melting point in the range of 345-349°C. This high melting point suggests robustness under elevated temperatures, a property often advantageous in material science applications. The molecular formula, C42H34Si2, reveals a structure featuring two triphenylsilyl groups attached to a central benzene ring at the meta positions.

The synthesis of 1,3-bis(triphenylsilyl)benzene is a key aspect of its availability and application. Typically, this compound is prepared through reactions involving organometallic intermediates or palladium-catalyzed cross-coupling reactions. A common route involves the reaction of triphenylsilyl chloride with a dihaloarene, such as 1,3-dibromobenzene, often in the presence of a suitable catalyst and base. The efficiency and yield of these synthetic methods are crucial for providing high-purity material, often required at levels of 98% or more for demanding applications like OLEDs.

NINGBO INNO PHARMCHEM CO.,LTD highlights that the meticulous control over reaction conditions and purification techniques is what allows for the production of high-grade silane 1,3-phenylenebis[triphenyl]. This attention to detail in synthesis ensures that the compound meets the stringent specifications required for its advanced applications, particularly in the electronics sector. Further research into optimizing these synthesis routes continues to be an area of interest for chemical manufacturers and researchers.
