碳硼烷是一类对空气、热和化学作用稳定的有机硼化合物。到目前已制得了几百个各种类型的碳硼烷衍生物,但关于其醚类衍生物则报导得很少,对称性的醚类衍生物几乎未见报导。就合成方法而言,直接由炔化物合成1,2-二碳对称取代的碳硼烷也是少见的。 我们由炔化物与双-(二乙硫醚)合十二氢癸硼烷直接合成了两个新的对称性o-碳硼烷醚类衍生物,扩展了用直接法合成o-碳硼烷衍生物的途径。这类化合物按如下反 Carborane is a class of organoboron compounds that are stable to air, heat and chemicals. So far, hundreds of various carborane derivatives have been prepared, but little reports have been reported on their ether derivatives. Symmetrical ether derivatives have hardly been reported. As far as the synthesis method is concerned, it is also rare to synthesize a 1,2-dicarbon-symmetrically substituted carborane directly from the alkynyl compound. We directly synthesized two novel o-carborane ethers derivatives from acetylide and bis- (diethyl sulfide) dodecahydrobidecaborane, and expanded the direct synthesis of o-carborane Derivatives approach. These compounds are as follows
