Cas no 448211-45-8 (2-(1-Cycloocten-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane)

2-(1-Cycloocten-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is a cyclic boronate ester featuring a cyclooctene moiety, commonly employed in Suzuki-Miyaura cross-coupling reactions. Its stable dioxaborolane framework enhances shelf life and handling, while the strained cyclooctenyl group offers reactivity in transition-metal-catalyzed transformations. The tetramethyl substitution on the borolane ring improves steric protection, reducing unwanted side reactions. This compound is particularly useful in the synthesis of complex organic molecules, including pharmaceuticals and agrochemicals, due to its compatibility with diverse functional groups. Its crystalline solid form ensures precise measurement and reproducibility in synthetic applications.
