The synthesis, structure and catalytic activity of a benzene-bridged divanadium complex were comprehensively studied. The reduction of (Nacnac)VCl2(1) (Nacnac = (2,6-iPr2C6H3NCMe)2HC) supported by β-diketiminate with potassium graphite (KC8) by employing benzene as the solvent allows access to the benzene-bridged inverted-sandwich divanadium complex (μ-η6:η6-C6H6)[V(Nacnac)]2(2a), which can catalyze alkene alkylarylation with hypervalent iodine(iii) reagents (HIRs)viadecarboxylation to generate regioselectively diverse indolinones. Furthermore, the mild nature of this reaction was amenable to a wide range of functionalities on alkenes and HIRs. Mechanistic studies revealed a relay sequence of decarboxylative radical alkylation/radical arylation/oxidative re-aromatization.

Azacyclo-and azabicycloalkanone peptidomimetics were synthesized regio-and diastereoselectively by iodoacetoxylation and transannular amidation reactions on unsaturated lactam precursors contingent on ring size olefin position solvent and hypervalent iodi

The reactivity of arenes with 4-methylquinoline (substitution) as a typical heteroaromatic base and phenyl vinyl sulfone (addition) as a typical activated olefin has been studied under thermal and irradiation conditions.The results suggest that electron-withdrawing groups on the aromatic ring in arenes are detrimental to reactions.The crystal structures of arenes 10 and 1e are reported.
