auxiliaryin
Auxiliaryin is a fictional organic compound used in schematic discussions of organometallic catalysis as a modular, removable auxiliary ligand. In many teaching and theoretical contexts, auxiliaryin serves to illustrate how a temporary coordinating molecule can steer reactivity, selectivity, or stereochemistry during a catalytic cycle, then be detached without altering the final product.
Structure and properties are designed to be modular. Auxiliaryin is depicted as a multi-dentate ligand containing
Synthesis and tuning are described in generic terms. In examples, auxiliaryin arises from modular building blocks
Applications include illustrative use in enantioselective transformations, regiodetermination in cross-couplings, and control of diastereoselectivity in complex
