1-Chloro-2-ethynylbenzene is a chlorinated benzene derivative.1-Chloro-2-ethynylbenzene may be used in the synthesis of 4-(2-chlorophenylethynyl)-3-methyl-5-phenylisoxazole.
1-Chloro-2-ethynylbenzene serves as a versatile building block in transition-metal-catalyzed coupling reactions, enabling efficient access to biaryl and heterocyclic scaffolds. Its ortho-chloro substituent provides regioselective functionalization via palladium-catalyzed cross-coupling, while the terminal alkyne moiety supports Sonogashira and Glaser-type homocoupling processes. The compound exhibits good bench stability and facilitates straightforward purification, making it well-suited for iterative synthetic sequences in medicinal chemistry and materials science applications.
