Elaborating amines via C-H functionalization has been an important area of research over the past decade but has generally relied on an added directing group or sterically hindered amine approach. Since free-amine-directed C(sp3)-H activation is still primarily limited to cyclization reactions and to improve the sustainability and reaction scope of amine-based C-H activation, we present a strategy

requires derivatization at nitrogen with a directinggroup. Transientdirectinggroups (TDGs) permit C−H functionalization in a single operation, without needing these additional steps for directinggroup installation and removal. Here we report a palladium catalyzed γ‐C−H arylation of amines using catalytic amounts of alkyl acetals as transientactivators (e.g. commercially available (2,2‐dimethoxyethoxy)benzene)

N-unprotected aliphaticamines represents one of the most efficient and straightforward strategies for amine synthesis. Despite some recent progress in this field, the NH2-directed γ-C(sp3)-H arylation of primaryaliphaticamines except α-amino esters remained an unmet challenge. In this report, we established a simple and efficient method for site-selective C(sp3)-H arylation of primaryaliphaticamines by aryl

functionalization of aliphaticamines is of great importance in organic and medicinal chemistry research. Several methods have been developed for the direct sp3 C–H functionalization of secondary and tertiary aliphaticamines, but site-selective functionalization of primaryaliphaticamines in remote positions remains a challenge. Here, we report the direct, highly site-selective γ-arylation of primary alkylamines
