Application

Silicon amine protocol (SLAP) reagents, in conjunction with aldehydes and ketones, form N-unprotected piperazines via photocatalytic cross-coupling with Ir[(ppy)2dtbbpy]PF6 (747769). Heteroaromatic, aromatic, and aliphatic aldehydes are well tolerated, as are structurally and stereochemically complex SLAP reagents. This product was introduced in collaboration with the Bode Research Group and provides a tin-free alternative to SnAP (tin amine protocol) reagents for piperazine synthesis.

Photocatalytic coupling of aldehydes and silicon amine protocol (SLAP) reagents enables the simple, scalable synthesis of substituted morpholines, oxazepanes, thiomorpholines, and thiazepanes under continuous flow conditions. Key to the success of this process is the combination of an inexpensive organic

Redox neutral photocatalytic transformations often require careful pairing of the substrates and photoredox catalysts in order to achieve a catalytic cycle. This can limit the range of viable transformations, as we recently observed in attempting to extend the scope of
