  • La déshydratation du trichlorométhyl-2-butanol-2
    作者:A. F. Thomas、E. Palluy、B. Willhalm、M. Stoll
    DOI:10.1002/hlca.19630460626
    日期:——
    The dehydration products of 2-trichloromethyl–2-butanol are the 2-trichloro-methyl–1-and -2-butenes. The first of these easily rearranges to 1, 1-dichloro-2-chloro-methyl-1-butene, but the allyl rearrangement product from the other is highly reactive, and gives further transformation products under the conditions used for the rearrangement.

  • Synthesis of methyl β-alkylcarboxylates by Pd/diphosphine-catalyzed methoxycarbonylation of methylenealkanes RCH2CH2C(R)=CH2
    作者:Ilya E. Nifant’ev、Nadezhda T. Sevostyanova、Sergey A. Batashev、Alexey A. Vinogradov、Alexander A. Vinogradov、Andrei V. Churakov、Pavel V. Ivchenko

    日期:2019.7
    A series of methylenealkanes RCH2CH2(R)C = CH2 (R = n-butyl, n-hexyl, isopropyl and isobutyl), which are products of selective zirconocene-catalyzed dimerization of alpha-olefins, were introduced into Pd-catalyzed methoxycarbonylation. With the use of 5-methyleneundecane (1-hexene dimer) as a substrate, the roles of protic acid, Lewis acid and molecular hydrogen were established for model Pd(ll)/PPh3 and Pd(II)/diphosphine catalysts.A series of bridged diphosphines were studied as catalyst components L in PdCl2/L-catalyzed methoxycarbonylation in the presence of H-2. One of the nine diphosphines studied, trans-2,3-bis(diphenylphosphinomethyl)norbomane, demonstrated the best catalytic results in terms of catalytic activity, selectivity and isolated yields of the products. Under the optimized conditions during 24 h experiments, dimers RCH2CH2(R)C = CH2 were transformed to methyl carboxylates RCH2CH2(R)CHCH2COOMe with 99 +% regioselectivity; isolated yields were 62-81%.In that way, the catalytic methoxycarbonylation of synthetically available methylenealkanes is an effective approach to branched carboxylic acids, with high prospects for practical application.

    been found that phosphinic acids 8–12 surpass di(2-ethylhexyl)phosphoric acid (extractant P204) in non-selective Ln3+ extractability (Ln = La, Pr, Nd, Dy and Lu). Significantly higher selectivity for heavy lanthanide extraction (Ln = Dy, Lu), compared to that of P204, is achieved by using a minimal excess of disubstituted phosphinic acids 13–24. Acid 13, which contains two branched substituents, demonstrated
