• Preparation of tetraketones

  A method of preparing tetraketone precursors which are useful in the production of high temperature resistant polyquinoxaline resins. Suitable diketones are oxidized with a halogenating agent, such as cupric halide or hydrogen bromide, and dimethylsulfoxide to produce the corresponding tetraketone. The tetraketones which can be produced by the instant process have the formula: ##STR1## wherein R is hydrogen or an aryl, substituted aryl, heterocyclic or substituted heterocyclic radical and R' is an aryl, substituted aryl, arylalkyl, arylether, arylthioether, arylsulfoxide, arylsulfone, heterocyclic or substituted heterocyclic radical.

  一种制备四酮前体的方法，这些前体在生产高温耐磨聚喹噁唑树脂中很有用。适当的二酮通过氯化剂（如氯化铜或溴化氢）和二甲基亚砜氧化，产生相应的四酮。通过这种方法可以生产的四酮具有如下结构式：##STR1## 其中R为氢或芳基、取代芳基、杂环或取代杂环基，R'为芳基、取代芳基、芳基烷基、芳基醚、芳基硫醚、芳基亚砜、芳基砜醚、杂环或取代杂环基。

• DMSO–PdI2 as a powerful oxidizing couple of alkynes into benzils: one-pot synthesis of nitrogen-containing five- or six-membered heterocycles

  PdI2 in DMSO promoted the oxidation of functionalized diarylalkynes into benzil derivatives in excellent yields. This new oxidation reaction was achieved with short reaction times and low loading of palladium catalyst. This efficient catalytic process has been applied successfully to the one-pot construction of a series of nitrogen-containing heterocycles of biological interest according to a tandem oxidation-nitrogen nucleophiles condensation-cyclization.
