Match each transformation to its named preparation: aryl+alkyl halide coupling with Na, diazonium-to-aryl-halide via Cu(I) salt, and alkyl-halide-to-fluoride via a metal fluoride.

(i) C6H5Br+2Na+CH3Br→C6H5−CH3+2NaBrC_6H_5Br + 2Na + CH_3Br \rightarrow C_6H_5-CH_3 + 2NaBr — an aryl halide reacting with an alkyl halide and sodium metal (dry ether) to couple them, forming a new C–C bond between the ring and an alkyl group, is the Wurtz–Fittig reaction.
