    Controlled Radical Polymerization of Vinyl Acetate with Cyclopentadienyl Chromium β-Diketiminate Complexes: ATRP vs OMRP
    摘要:
    The ability of compounds CpCr(II)(nacnac(Ar.Ar)) (Ar = Dipp, 1; Xyl, 2)10 catalyze the atom transfer radical polymerization (ATRP) of vinyl acetate has been explored using methyl 2-chloropropionate as initiator. Polymerizations were also carried out under reverse ATRP conditions with thermal initiation by 2,2'-azobis(4-methoxy2,4-dimethylvaleronitrile) (V-70) in the presence of compounds CpCr(III)(nacnac(Ar.Ar))Cl (Ar = Dipp, 3; Xyl, 4). All data suggest that these processes are in fact proceeding by organometallic-mediated radical polymerization (OM RP). Stoichiometric reactions between complex 2 and the chlorinated compounds CH3CH(Cl)COOOCH(3), ClCH(2)COPh, CH(3)CH-ClOOCCH(3), ClCH(2)OOC/Bu, and ClCH(2)tBu in the absence of monomer aid in the interpretation of the polymerization results. The first two substrates show rapid one-electron oxidative additions to generate 4 and O-bonded Cr(III) products, whereas the third and fourth substrates add much more slowly to generate 4 and C-bonded Grill products; ClCH(2)tBu does not react. DFT calculations on the competitive radical trapping, processes (activation barriers and relative stability of the products) confirm the kinetic and thermodynamic preference for metal carbon bond formation to generate the dormant species of OM RP.

    摘要:
    制备了一系列Cr(III)半三明治β-二酮化合物,CpCr [(ArNCMe)2 CH] X,X = I(2),CH 3(3)或Cl(4)。与先前传达的Ar = 2,6- i Pr 2 C 6 H 3(Dpp,a)的配合物相比,具有较少空间需求配体的Cr(III)配合物,例如Ar = 2,6-Me 2 C 6 H 3( Xyl,b),2,4,6-Me 3 C 6 H 2(Mes,c)或2,6-Et 2 C 6H 3(Dep,d)更容易通过盐复分解反应合成。通过用一半当量的碘氧化相应的Cr(II)物种CpCr [(ArNCMe)2 CH] 1b - d制备碘化物2b - d。由两步一锅法从无水CrCl 3制备氯化铬(III)络合物CpCr [(ArNCMe)2 CH] Cl 4c - d。MeMgI与任一的Cr(III)氯化物或碘化物的前体反应得到在Cr(III)络合物甲基CPCR [(ArNCMe)2
