Application

Pentylmagnesium bromide solution is a Grignard reagent that can be used in the preparation of:
  • Alkanes via Ni or Cu-catalyzed cross-coupling reaction with alkyl fluorides.
  • Hydroxypiperidinones via the addition-cyclization-deprotection process of aldimines.

It can also be used as a reagent to synthesize a key intermediate by olefin alkylation in the total synthesis of alkaloid, (+)-hyperaspine , and surface alkylation of H-terminated Si (111), by Si-C bond formation.
