  Anchoring sulfonic acid on silica surface through Si C bond for immobilization of catalyst for polyketone synthesis

  摘要：

  Sulfonic acid groups were anchored on a silica surface through robust Si-C bonds. The successive treatment of dehydroxylated silica with benzylmagnesium chloride and H2SO4 resulted in the surface tethering of -CH2C6H4SO3H groups at a high coverage rate (0.50-CH2C6H4SO3H/nm(2)). The pore structure of the silica remained unchanged during this surface-modification process. Next, the -CH2C6H4SO3H groups on the surface were successfully used for preparing a supported catalyst for CO/ethylene copolymerization; the Si-CH2C6H4SO3H groups on the surface were reacted with [1,3-bis(di(2-methoxyphenyl)phosphino)propane]Pd-( OAc)(2) to generate dicationic palladium species, which were anchored on the silica surface through ionic interactions with the sulfonate anions generated on the surface. The supported catalyst prepared in this way exhibited a high activity (up to 43 kg/g-Pd or 0.61 kg/g-cat) with respect to CO/ethylene copolymerization. The morphology of the obtained polymer particles replicated that of the silica particles. Thus, a polymer powder that exhibited a high bulk density (0.30 g/mL) could be obtained while causing minimal reactor fouling. (C) 2015 Elsevier B.V. All rights reserved.

  Abstract A novel reaction for the synthesis of sulfinic acids, sulfinic acids esters, sulfonic acids and S -alkyl alkanethiosulfonates from olefins, SO 2 and hydrogen will be described. Due to its similarity to hydroformylation, this reaction will be called hydrosulfination. Various palladium complexes ([Pd(NCCH 3 ) 2 (R 2 P(CH 2 ) n PR 2 )](BF 4 ) 2 (RPh, n =2–5; RMe, o -(C 6 H 4 OMe), n =3) have

  Neutral and bis-cationic palladium(H) complexes with 1,2-bis(di(2-methoxyphenyl)phosphino)ethane (o-MeO-dppe) and 1,3-bis(di(2-methoxyphenyl)phosphino)propane (o-MeO-dppp) have been synthesized and employed to catalyze the CO-ethylene copolymerization reaction in either protic or aprotic solvents. A comparison of the catalytic performance of these complexes with that of analogous precursors stabilized by 1,2-bis(diphenylphosphino)ethane (dppe) and 1,3-bis(diphenylphosphino)propane (dppp) ligands has shown significant differences in terms of catalytic productivity and molecular weight. In situ and operando high-pressure NMR experiments have provided valuable information on catalysis resting states and intermediates and have contributed to rationalize the observed productivity as well.

  The influence on the productivity of[PdCl2(dapp)] in H2O-CH3COOH in the CO-ethene copolymerization and on the LVN of the copolymer of the following reaction parameters has been studied: (i) composition of the H2O-CH3COOH reaction medium; (ii) temperature; (iii) CO/ethene ratio at a given total pressure; (iv) total pressure at fixed ratio CO/ethene = 1/1; (v) CO or ethene partial pressure at a given pressure of one monomer; (vi) reaction time. High molecular weight PKs are obtained under high pressure with the monomers in the ratio 1/1 at relatively low temperature and with a H2O/CH3COOH 40-50% with productivity ranging from 4 to 20 kg PK(g Pd h)(-1).The relation between productivity and LVN has been discussed in the light of the key steps of the catalytic cycle.
