Synthesis of arylboronates by boron-induced ipso-deantimonation of triarylstibanes with boron trihalides and its application in one-pot two-step transmetallation/cross-coupling reactions
The reaction of triarylstibanes (1) with borontrihalides (BCl3, and BBr3) afforded arylboron dihalides (2) by utilizing all the three aryl groups on the antimony. Boron intermediates (2) were transformed to arylboronates (3) in good to excellent yields by treatment with methanol and 1,3-propanediol. Further, the Pd-catalyzed reactions of 2 with organic halides such as 1-bromonaphthalene and benzoyl

Triarylantimony(V) derivatives Ar3SbX2 (X=Hal or acyloxy) were prepared by reaction of Ar3Sb with equimolar amounts of a peroxide ROOH (R=t-Bu, H) in the presence of an acid or an anhydride in good to excellent yields. Ar3Sb(O2CR)2 are mild and efficient C-arylation reagents of unsaturatedcompounds (methyl acrylate, styrene, 2-phenylpropene and acrylonitrile) under palladium catalysis at 50 °C, with

Triarylstibines react with α,β-unsaturated ketones and aldehydes in acetic acid at room temperature in the presence of AgOAc and a catalytic amount of Pd(OAc)2 to afford the conjugate addition products (the formal hydroarylated compounds to an olefinic part) in good yields. In contrast, diarylantimony chlorides, arylantimony dichlorides, and diphenylantimony acetate react with the enones and enals

Triarylantimony Ar3Sb (Ar = 4-FC6H4, 3-MeC6H4) is oxidized by hydrogen peroxide to form tetranuclear complexes [(4-FC6H4)2SbO]4(O2)2 and [(3-MeC6H4)2SbO]4(O2)2 (as a DMSO solvate). The structure of the resulting compounds was examined by single crystal X-ray diffraction analysis.
