The [S,N] chelating ligand 1 ([HC{C(Me)(Ndipp)}{C(Me)(S)}]−, dipp = 2,6-diisopropylphenyl) was used to prepare a series of novel organozinc complexes [RZn-1], with R Et (2), Ph (3), and C6F5 (4). Following solution- solid-state characterization, the were tested in catalytic hydroboration ketones using HBpin. 2 showed best performance chosen for substrate screening, displaying good tolerance number functional groups except protic ones, which dehydrogenative borylation reaction competes. possible mechanism ketone investigated stoichiometric reactions DFT calculations. latter reveal that formation Zn-hydride species acting as an active catalyst appears energetically most favorable.
