Unraveling C‐Selective Ring‐Opening of Phosphiranes with Carboxylic Acids and Other Nucleophiles: A Mechanistically‐Driven Approach Open
Phosphiranes are weak Lewis bases reacting with only a limited number of electrophiles to produce the corresponding phosphiranium ions. These salts are recognized for their propensity to undergo reactions with oxygen pronucleophiles at the…
