Abstract Deuterium labeling compounds play a crucial role in organic and pharmaceutical chemistry. The synthesis of such typically involves deuterated building blocks, allowing for the incorporation deuterium atoms functional groups into target molecule single step. Unfortunately, limited availability synthetic approaches to synthons has impeded progress this field. Here, we present an approach utilizing alkyl-substituted thianthrenium salts that efficiently selectively introduce at α position alkyl chains through pH-dependent HIE process, using D 2 O as source. resulting α-deuterated salts, which bear two atoms, exhibit excellent selectivity electrophilic substitution reactions. Through situ formation isotopically labelled halides, these demonstrate compatibility series metallaphotoredox cross-electrophile coupling with (hetero)aryl, alkenyl, bromides, other salts. Our technique allows wide range substrates, high incorporation, precise control over site insertion within benzyl position, allylic or any chain between, well neighboring heteroatoms. This makes it invaluable synthesizing various deuterium-labeled compounds, especially those significance.
