Sodium Triacetoxyborohydride: Overview
Sodium triacetoxyborohydride (STAB) is a selective reducing agent commonly used in organic synthesis, particularly for the reductive amination of aldehydes and ketones with amines. It is milder than other reducing agents like sodium borohydride (NaBH₄) and is often preferred due to its selectivity and tolerance of a wide range of functional groups.
