用2，3，5，6-四甲基-1，4-双（三甲基硅基）-1，4-二氮杂-2，5-环己二烯还原带有4-tBu-2，6-[CH（SiMe 3）2]2-C6 H 2（Tbb）基团的二溴铋硫和二溴锑化氢，分别得到相应的稳定的二铋烯（TbbBi <$BiTbb）和二苯乙烯（TbSb <$SbTbb）.得到的唯一副产物是易于除去的四甲基吡嗪和溴三甲基硅烷。重要的是，在该还原中没有产生无机盐：即，这是一种独特的无无机盐的方法，用于合成在较重的主族元素之间具有多重键的化合物。
A dibromobismuthine and a dibromostibine that bear 4-tBu-2,6-[CH(SiMe3)2]2-C6H2(Tbb) groups were reduced with 2,3,5,6-tetramethyl-1,4-bis(trimethylsilyl)-1,4-diaza-2,5-cyclohexadiene to afford the corresponding stable dibismuthene (TbbBiBiTbb) and the distibene (TbbSbSbTbb), respectively. The only byproducts obtained were easily removable tetramethylpyrazine and bromotrimethylsilane. Importantly, inorganic salts were not generated in this reduction: i.e., this is a unique inorganic-salt-free method for the synthesis of compounds with multiple bonds between heavier main-group elements.
