资源简介：
A new
thorium monoalkyl complex, Th(CH2SiMe3)(L3) (L = MeC(NiPr)2)
(2), undergoes insertion of chalcogen atoms resulting
in a series of thorium chalcogenolate complexes, Th(ECH2SiMe3)(L3) (E = S, SS, Se, Te; 5–8). Complex 6 represents the first
alkyl disulfide thorium species and illustrates the ability of 2 to undergo controllable, stoichiometric atom insertion.
All complexes have been characterized by 1H and 13C NMR spectroscopy, FTIR, EA, and melting point, and in the case
of 1, 2, and 4–8, X-ray crystallography. Insertion was achieved by balancing
the thermodynamic driving force of chalcogenolate formation versus
the BDE of the pnictogen–chalcogen bond in the transfer reagent.
Utilizing Me3NO as an oxygen atom transfer reagent led
to C–H activation and SiMe4 extrusion rather than
oxygen atom insertion, resulting in the alkoxide complex Th(OCH2NMe2)(L3) (4).
