After many attempts, novel 4-t-butyl-2,6-dipyrimidy1-1-bromobenzene was successfully synthesized by the reaction of 4-t-butyl-2,6-diiodo-1-bromobenzene with 2-sytannylpyrimidine in the presence of Pd catalyst. Since the yield is very low, the synthetic procedures should be revised in near future. With the target precursor, 4-t-butyl-2,6-dipyrimidy1-1-bromobenzene, in hand, Pd and Pt were introduced as central atoms. The structures were characterized by X-ray analysis, and the Pd (or Pt)-N (Pyrimidine) was found to be strong on the basis of the fact that the coalescence of NMR signals was not observed up to high temperatures.

以4-叔丁基-2，6-二碘-1-溴苯为原料，在钯催化剂作用下，与2-辛基嘧啶反应，合成了4-叔丁基-2，6-二嘧啶-1-溴苯。由于产率很低，因此在不久的将来，应修改合成程序。以目标前体4-叔丁基-2，6-二嘧啶基-1-溴苯为原料，引入Pd和Pt作为中心原子。通过X射线分析表征了结构，并且基于在高温下未观察到NMR信号的聚结的事实，发现Pd（或Pt）-N（嘧啶）是强的。
