2 with the group 13 trialkyls AlMe3, AlEt3, GaMe3, GaEt3 and InMe3, metallation of the ethynyl group afforded compounds 4–8 under extrusion of the corresponding alkane. The resulting products were characterised by elemental analyses and NMR spectroscopy. Compounds 4 and 8 were crystallized from THF and were yielded as monomers with coordinated THF molecules. The gallium compound 7 could be crystallised
4-乙炔基-2,6-二甲基吡啶,(2,6-Me 2)(4-HC C)C 5 H 2 N(2)与B(C 6 F 5)3的反应提供了两性离子[( 2,6-Me 2)(4-(C 6 F 5)3 BC C)C 5 H 2 NH](3)经由去质子化途径。通过治疗的2与组13三烷基阿尔梅3,ALET 3,游戏3,GaEt 3和InMe 3乙炔基的金属化在相应烷烃的挤出下提供化合物4-8。所得产物通过元素分析和NMR光谱表征。从THF中结晶出化合物4和8,并以具有配位THF分子的单体形式产生。镓化合物7可以从苯中结晶出来,并作为配位聚合物提供。通过单晶X射线衍射实验确定了这三种化合物(4 ·THF,7和8 ·2THF)的结构。铝化合物4和5显示出它们的取代基的再分布反应。
