  摘要：

  The present invention relates to a catalytic process for the partial reduction of esters or lactones to silyl acetals, which upon hydrolysis give aldehydes, using silanes as reducing agents, preferably triethylsilane (TESH) or 1,1,3,3-tetramethyldisiloxane (TMDS), in the presence of novel triaryl borane type catalysts. More specifically, the present invention relates to novel triaryl borane type catalyst compounds of formula (I) which can be applied for the partial reduction of an ester or lactone to a silyl acetal. In the formula R1, R'1, R5, R'5and R6are groups having small steric demand and R10is a group having large steric demand. The invention also relates to a method for the preparation of aldehydes or lactols wherein said method comprises the following steps: i) an ester or lactone is reacted with a silane in the presence of a compound of formula (I) to obtain a silyl acetal; ii) the obtained silyl acetal is hydrolysed with acidic or fluoride containing reagent to form an aldehyde or lactol; iii) optionally, the resulting aldehyde or lactol is separated and purified.

• Mechanistic Origins of Regioselectivity in Cobalt-Catalyzed C(sp2)-H Borylation of Benzoate Esters and Arylboronate Esters
  作者：Tyler P. Pabst、Linda Quach、Kaitlyn T. MacMillan、Paul J. Chirik

  日期：2021.1

  Synthetic and mechanistic investigations into the C(sp2)-H borylation of various electronically diverse arenes catalyzed by bis(phosphine)pyridine (iPrPNP) cobalt complexes are reported. Borylation of various benzoate esters and arylboronate esters gave remarkably high selectivities for the position para to the functional group; in both cases, this regioselectivity was found to override the ortho-to-fluorine

  报道了双（膦）吡啶 ( iPr PNP) 钴配合物催化的各种电子多样性芳烃的 C(sp 2 )-H 硼化反应的合成和机理研究。各种苯甲酸酯和芳基硼酸酯的硼化反应对官能团的对位产生了非常高的选择性；在这两种情况下，发现这种区域选择性覆盖了之前报道的 ( iPr PNP)Co 硼化催化剂的邻位到氟的区域选择性，这是由 C(sp 2 )-H 氧化加成的热力学控制引起的。机理研究支持导致对位到酯和对位的途径分别通过动力学控制 BH 和 C(sp 2 -H) 氧化加成对硼酸酯的选择性。一种特别缺电子的氟化芳基硼酸酯的硼化导致 C(sp 2 )-H 氧化加成的加速和伴随的区域选择性反转，表明催化循环各个步骤的相对速率的细微变化可以实现独特且可切换的位点选择性。

  The rhodium(I)-catalyzed reaction of alkynes with 2-bromophenylboronic acids in the presence of paraformaldehyde resulted in a CO gas-free carbonylative cyclization, yielding indenone derivatives. [RhCl(BINAP)]2 and [RhCl(cod)]2 were responsible for the decarbonylation of formaldehyde and the subsequent carbonylation of alkynes with 2-haloboronic acids, respectively, leading to efficient whole carbonylation

  reaction of alkynes with 2-bromophenylboronic acids under nitrogen gives naphthalene derivatives, in which two molecules of alkynes are incorporated. A vinylrhodium complex similar to II can also be generated by a different route by employing 2-bromophenyl(trimethylsilyl)acetylene and arylboronic acids in the presence of Rh(I) complex as the catalyst, resulting in the formation of indenones.

  4-Methylenechromanes were prepared via a three-step process from 2-borylated α-methylstyrenes. This sequence is based on a key glyoxylate-ene reaction catalyzed by scandium(iii) triflate. The resulting γ-hydroxy boronates, which cyclise to seven-membered homologues of benzoxaborole on silica gel, were cleanly oxidized with sodium perborate, and then cyclised under Mitsunobu conditions. Additionally

• Use of 2-Bromophenylboronic Esters as Benzyne Precursors in the Pd-Catalyzed Synthesis of Triphenylenes
  作者：José-Antonio García-López、Michael F. Greaney

  日期：2014.5.2

  aryl boronates are introduced as aryne precursors for transition-metal-catalyzed transformations. On treatment with tBuOK and Pd(0), metal-bound aryne intermediates are formed that undergo effective trimerization to form useful triphenylene compounds. For meta-substituted arynes, the 3:1 product ratio in favor of non-C3 symmetric material is indicative of a benzyne mechanism.
