  摘要：

  Phenylthio(trimethylsilyl)methane, phenylthiosbis(trimethylsily)methane, methoxy(trimethysily)methane, and methoxybis(trimethylsilyl)methane are depronated and the resulting anions are alkylated with electrophiles such as organic halides. The alkylation products are readily converted into the corresponding dimethyl acetals or methyl esters by electrochemical oxidation in methanol.

• Highly effective tandem hydroformylation–acetalization of olefins using a long-life Brønsted acid–Rh bifunctional catalyst in ionic liquid–alcohol systems

  A robust and highly effective tandem hydroformylation–acetalization of olefins using a Brønsted acid–Rh bifunctional catalyst (ARBC) in ionic liquid–alcohol systems is reported. The key feature of the ARBC is its use of a zwitterionic phosphine ligand bearing an amino acid tag. This novel ARBC shows an excellent catalytic efficiency and a long service life without a significant drop in both the hydroformylation efficiency and the acetalization efficiency or Rh loss for more than seventeen cycles. We believe that the long-term high activity and acetal selectivity mainly benefit from the synergy between the acidic active site and the Rh active site on the ARBC and the highly effective immobilization and recycling of ARBC in ionic liquid–alcohol systems due to the strong affinity of ARBC for the ionic liquid.

  报道了一种在离子液体-醇体系中使用布朗斯台德酸-铑双功能催化剂(ARBC)对烯烃进行高效且稳定的串联氢甲酰化-缩醛化反应。ARBC的关键特点是其采用了带有氨基酸标记的二性磷配体。这种新型ARBC表现出卓越的催化效率和长寿命，在超过十七个循环后，氢甲酰化效率、缩醛化效率以及铑损失均未出现显著下降。我们认为，长期高活性和缩醛选择性主要得益于ARBC上酸活性位点与铑活性位点之间的协同作用，以及由于ARBC对离子液体的高亲和性，实现了在离子液体-醇体系中高效固定化和循环利用。
