The mixture was stirred at 50 °C for 3 h.The mixture was evaporated, and the product was isolated bysilica gel column chromatography to give the title compound 3(5.50 g, 95%) as white solid; mp 85-88 °C. 1H NMR (500 MHz,CDCl3): δ = 3.45-3.64 (8H, m), 5.60 (1H, s). 13C NMR (CDCl3) δ =38.3, 42.5, 45.6, 46.0, 163.0. HRMS (APCI): m/z + calcdfor C5H9ClN2NaO, 171.03011; found: 170.03091.95%With thionyl chloride In chloroform at 20℃; for 5h;Experimental Procedure5.09 g (39.1 mmol) of 1- (2-hydroxyethyl) -2-imidazolidinone was dissolved in 10 mL of chloroform in a 25 mL recovery flask, and 3.1 mL (42 mmol) of thionyl chloride was slowly added dropwise thereto. After stirring at room temperature for 5 hours, chloroform and residual thionyl chloride were distilled off under reduced pressure. The residue was purified by silica gel chromatography (developing solution: chloroform / methanol = 10/1) to obtain 3.95 g (yield: 68%) of colorless solid 1- (2-chloroethyl) -2-imidazolidone68%With thionyl chloride In dichloromethane at 20 - 40℃; for 3.08333h;66%

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...
