  Facile Multistep Synthesis of Isotruxene and Isotruxenone

  摘要：

  Three multistep approaches toward facile syntheses of isotruxene (1) and isotruxenone (3) are reported. The ortho-para conjugated backbone in the precursor 4 was constructed by either Co-catalyzed [2 + 2 + 2] cyclotrimerization or the [4 + 2] Diels-Alder reactions. The regioselectivity of the triple intramolecular Friedel-Crafts acylation of 4 plays the key role in determining the overall yield. Compared to the previous one-step method, the current approaches are more efficient in terms of product yield (27-36% vs 4-18%) and purification (i.e., free of column chromatography).

  The invention provides process for the preparation of a branched poly(arylcarbonate) suitable for use in blow molding, which process comprises subjecting a linear (arylcarbonate) crystallized oligomer derived from a dihydroxy diaryl compound and a diarylcarbonate to solid state polycondensation by heating the oligomer at a temperature, which is higher than its glass transition temperature but below its melting point, in the presence of a multifunctional phenol and, optionally, a catalyst, under an inert atmosphere.

  本发明提供了制备适用于吹塑成型的支化聚(芳基碳酸酯)的工艺，该工艺包括在惰性气氛下，将由二羟基二芳基化合物和二芳基碳酸酯衍生的线性(芳基碳酸酯)结晶低聚物在高于其玻璃化温度但低于其熔点的温度下加热，使其固态缩聚。
