应用
When used with aliphatic or aromatic aldehydes, this silicon amine protocol SLAP reagent enables the photomediated synthesis of thiomorpholines and thiazepanes. For photocatalytic cross-coupling with this SLAP Reagent, Ir[(ppy)2dtbbpy]PF6 (747769) is used with a recommended starting combination of Lewis acids Bi(OTf)3 (633305) and Cu(OTf)2 (283673) prior to subsequent substrate-specific optimization. This product was introduced in collaboration with the Bode Research Group and provides a tin-free alternative to SnAP (tin amine protocol) reagents and is well-suited for scale-up reactions.

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

Silicon amine protocol (SLAP) reagents for photocatalytic cross-coupling with aldehydes and ketones to form N-unprotected piperazines have been developed. This blue light promoted process tolerates a wide range of heteroaromatic, aromatic, and aliphatic aldehydes and structurally and stereochemically complex SLAP

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
