Disconnection

Definition

Disconnection is a fundamental concept in organic synthesis that involves the strategic identification of key bonds to be broken or formed in order to transform one molecule into another. It is a critical step in retrosynthetic analysis, where chemists work backwards from a target molecule to identify suitable precursors and reaction steps.
