Treatment of 1,3,5-tris(3,3-dimethyl-1-butynyl)benzene, C6H3(C⋮C−CMe3)3, with di(neopentyl)gallium hydride, HGa(CH2CMe3)2, resulted in the addition of one Ga−H bond to each C⋮C triple bond (hydrogallation). Spontaneous condensation by the release of tri(neopentyl)gallium yielded a [3,3,3]-cyclophane derivative (1) with three tricoordinated Ga atoms in bridging positions.
1,3,5-三(3,3-二甲基-1-丁炔基)苯,C的治疗6 ħ 3(C⋮C-CME 3)3,与二(新戊基)氢化镓,HGA(CH 2 CME 3)2,导致每个C⋮C三键加成一个Ga-H键(氢化镓)。通过释放三(新戊基)镓自发缩合产生[3,3,3]-环烷衍生物(1),其在桥连位置具有三个三配位的Ga原子。
