  A catalyst composed of an organic phosphorus compound having a trivalent or pentavalent phosphorus atom and at least one carbon-phosphorus bonding or a combination of the organic phosphorus compound and a halogen atom-containing compound is effective for decarbonylation, that is, for releasing carbon monoxide from a compound containing a moiety of -CO-CO-O- in its molecular structure.

  一种由含有三价或五价磷原子的有机磷化合物和至少一个碳-磷键合或有机磷化合物与含卤原子的化合物的组合构成的催化剂对于脱羰基作用是有效的，即从含有分子结构中的-CO-CO-O-基团的化合物中释放一氧化碳。

  日期：2008.1.1

  An efficient method to synthesize functionalized tetraarylphosphonium salts is described. This palladium-catalyzed coupling reaction between aryl iodides, bromides, or triflates and triphenylphosphine generates phosphonium salts in high yields. The coupling is compatible with a variety of functional groups such as alcohols, ketones, aldehydes, phenols, and amides.

  A diaryl carbonate with a high degree of purity is produced at a high yield by (A) subjecting (a) a diaryl oxalate and a phenol compound or (b) an alkylaryl oxalate to transesterification reaction in one or two stages in the presence of a catalyst to prepare a diaryl oxalate, while removing a by-product from the reaction system; (B) collecting the diaryl oxalate from the resultant reaction product mixture of the step (A); (C) subjecting the diaryl oxalate to a decarbonylation reaction, preferably in the presence of a phosphorous compound-containing catalyst, to convert the diaryl oxalate to a corresponding diaryl carbonate, while removing a reaction by-product comprising carbon monoxide from the reaction system; and (D) collecting the diaryl carbonate from the reaction product mixture of the step (C).

  高纯度碳酸二芳基酯的制备方法是：(A)在催化剂存在下，将(a)草酸二芳基酯和苯酚化合物或(b)草酸烷基芳基酯在一个或两个阶段中进行酯交换反应，制备草酸二芳基酯，同时从反应体系中除去副产物；(B)从步骤(A)的反应产物混合物中收集草酸二芳基酯；(C) 将草酸二芳基酯进行脱羰基反应，最好是在含磷化合物催化剂存在下进行，以将草酸二芳基酯转化为相应的碳酸二芳基酯，同时从反应体系中除去由一氧化碳组成的反应副产物；以及 (D) 从步骤(C)的反应产物混合物中收集碳酸二芳基酯。
