Route of Synthesis (ROS)

Route of Synthesis (ROS) of TETRAVINYLSILANE CAS 1112-55-6

ConditionsYieldWith palladium(II) acetylacetonate; potassium fluoride In N,N-dimethyl-formamide at 130℃; under 1500.15 Torr; for 3h; Reagent/catalyst; Time; Hiyama Coupling; Inert atmosphere;Experimental ProcedureGeneral procedure: A mixture of organohalides (1a-h) (0.25mmol), vinysilanes 2a (0.3mmol) or 2c (0.075mmol), potassium fluoride (0.6mmol), and supported palladium NPs catalyst (Pd/substrate ratio 1mol%) was suspended in DMF (1ml). Then, the flask was evacuated under vacuum and refilled with argon. The evacuation/refilling cycle was repeated three times (pressure 2bar). The mixture was stirred at 130°C, and the reaction was monitored by GC and GC-MS. The reaction was performed for the time required ranging from 1.5 to 24h, to obtain the maximum yield of 3a-h products.93%

BCB (Benzocyclobutene): — Watson International Enables the Transition from Concept to Scalable Application

Benzocyclobutene (BCB) is an organic compound with a rigid molecular structure composed of a conjugated benzene ring and a four-membered ring. Its excellent thermal stability and electrical properties have made it a highly promising candidate for next-generation electronic materials. Historically, its industrial adoption has been constrained by high production costs, complex purification processes, and limited output. However, with growing demand in high-end applications and recent advances in upstream technology, BCB is now poised for industrial-scale deployment. Material Properties and Structural Advantages BCB (C₈H₈) is a non-polar molecule, free of ester, carboxyl, or amide groups, giving it excellent dielectric properties and low moisture absorption. Its dielectric constant (Dk) and dissipation factor (Df) remain stable across wide temperature and frequency ranges—key metrics for ensuring signal integrity in high-frequency, high-speed communication systems. Unlike conventional m...
