The anomalous responses of Mw to conversion and to comonomer stoichiometry, i.e., deviations from expected classic A−A + B−B step-growth polycondensation behavior, observed in poly(p-phenylene sulfide) synthesis from p-dichlorobenzene and sodium

The crystallization behaviour of poly(p-phenylene sulfide) (PPS) has been studied. Two PPS samples with 〈MW〉 = 44 K and 〈MW〉 = 64 K were fractionated by a process which selectively removes a portion of the low molecular weight species yieldin

The chemistry of poly(p-phenylene sulfide) (PPS) growth from Na 2 S and p-dichlorobenzene in NMP is dominated by the ionic S N Ar mechanism. Consistent with this mechanism are model reactions that obey discrete second-order reaction kinetics in both

Reaction of salts of HFe(CO)3PR3− (R = OMe, OEt, OPh, Me, Ph) with Ph3PAuCl leads to quantitative partitioning into H2Fe(CO)3PR3 and (Ph3PAu)2 Fe(CO)3PR3. The complex (Ph3PAu)2Fe(CO)3P(OEt)3 · Et2O crystallized in the monoclinic space group P21/n,

The relative reactivity of anionic transition metal carbonyl hydrides towards hydride transfer to monomeric metal carbonyls is consistent with an ionic route, generating, in the best-matched cases of electrophilic carbonyls (highest f CO or average v

Studies of intermolecular hydride transfer from coordinatively saturated HM(CO)4L- (M - Cr, W; L - GO, PR3) conclude the M-H functional group to be isolated and the gp 6 metal center to be inaccessible to entering substrates. In contrast the analogou
