Alkyl manganese pentacarbonyl compounds5MnR (R = CH3, p-CH2C6H4CH3, p-CH2C6H4OCH3) were synthesized by metalation of manganese pentacarbony potassium salt with corresponding alkyl halides in ether. Photolysis of these with 1-2 equivalent of (CH3)2(C6H5)SiH or (CH3)(C6H5)2SiH in C6D6 solution at 5℃ produces silyl manganese pentacarbonyl compounds5MnSi(C6H5)(CH3)2 and5MnSi(C6H5)2(CH3) respectively (yield 70-88%).

在钯触媒和三苯基磷的存在下，我们可利用炔基格林那试剂或炔基锂和简单的卤烷进行偶合，而这样的反应条件也能应用在苯基取代炔丙基硫缩酮衍生物的合成上。

An application of the test to the comparisons of the eleven sequenced arthropod mtDNAs revealed that most of the observed evolutionary models were homogeneous between the two mosquitoes but not between Daphnia pulex or Artemia Franciscan and the other arthropod, probably due to shifts to a high AT content.

在真实数据中，用11种节肢动物线粒体DNA的比较中发现，水蚤或卤虫与其他9种节肢动物以高百分比违背了同质性进化模型假设，显然是由于AT含量高而引起的，且在两种蚊子的线粒体DNA比较中发现，其满足同质性假设仅有7.69%。
