Application

Cyclohexylzinc bromide is an organozinc reagent, generally used in Negishi coupling. Examples include the cross-coupling of alkylzinc halides with aryl/heteroaryl halides using Pd-PEPPSI-IPent and nickel-catalyzed synthesis of 4-substituted coumarins.

It can react with the SO2 surrogate, 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) adduct (DABSO) to afford zinc sulfinate salts which can be alkylated to synthesize various useful sulfones.
