CYCLOPENTYLZINC BROMIDE Chemical Properties,Usage,Production

Uses

Cyclopentylzinc bromide is an organozinc reagent that can be used in:

• The synthesis of polyfunctional indoles by reacting with various aryldiazonium salts via Fischer indole synthesis.
• Negishi cross-coupling reactions with various haloarenes in presence of Pd-complex catalyst.
• The preparation of aryl alkyl ketones by alkylation of aryl N-methyl-N-tosyl or N-benzyl-N-(tert-butoxycarbonyl) amide derivatives in the presence of Ni catalyst and imidazolidinylidene ligand.
