Synthesis of Secondary Amines via Self-Limiting Alkylation of N-Aminopyridinium Salts
, 2023 Partial amine alkylation to prepare secondary amines is challenging due to the enhanced N-nucleophilicity that accompanies alkylation. Here we introduce N-aminopyridinium salts as ammonia surrogates for the synthesis of secondary amines via self-limiting
