We report details of our attempts to reduce the bulky carbazolyl diiodoalane [R-AlI]. The reducing agents employed include KC, CpCo and the Mg(I) compound [(BDI)Mg]. The use of KC allowed the spectroscopic observation of the alanediyl [R-Al]. With CpCo as the reducing agent, the alanediyl [R-Al] was obtained as a crystalline material in low yield, but paramagnetic impurities remained. When diiodoalane [R-AlI] was treated with [(BDI)Mg], no reduction but a 2 : 1 addition was observed.
我们报告了尝试还原庞大的咔唑基二碘代铝烷 [R-AlI] 的细节。所使用的还原剂包括 KC、CpCo 和 Mg(I)化合物 [(BDI)Mg]。使用 KC 允许对丙二酰基 [R-Al] 进行光谱观察。使用 CpCo 作为还原剂，丙二酰基 [R-Al] 以低产率获得结晶材料，但仍存在顺磁杂质。当二碘代铝烷 [R-AlI] 与 [(BDI)Mg] 处理时，观察到的不是还原而是 2:1 的加成。
