Scheme 1. Comparison of the Envisioned Photoredox-Mediated Radical Addition to Imines by Alkylsilicate Radical Precursors vs Standard Alkylation Approaches: (a) via Traditional Organometallic Reagents; (b) via Stoichiometric Generation of Radicals; (c) Alternate Photoredox-Based Approach Using Alkylsilicates.
