CYCLOHEXYLZINC BROMIDE Structural

What is CYCLOHEXYLZINC BROMIDE?

The Uses of CYCLOHEXYLZINC BROMIDE

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.

The Uses of CYCLOHEXYLZINC BROMIDE

It is used as primary and secondary intermediate.
