We then explored the use of a diverse set of commercially available gem-dichloroalkanes as carbene precursors in our reaction protocol, using 4-phenylstyrene as the coupling partner (Scheme 2). Deuterated dichloromethane was successfully employed, leading to the formation of the corresponding deuterated cyclopropane product (25b). Similarly, 1,1-dichloroethane was activated under the reaction conditions to afford the cyclopropane derivative (26b) in good isolated yield. Furthermore, the use of chloroform and deuterated chloroform provided products 27b and 28b, respectively, demonstrating the regioselective installation of a carbon-chlorine bond within the cyclopropane ring.
