(8) with 1,2-bis(dichloroboryl)benzene 9 affords exchange product 10, which on deprotonation followed by reaction with ZrCl4 gives the very labile o-phenylene-bridged bis(1-boratabenzene)zirconium dicholoride 6. A similar reaction sequence from 8 and 1,1-bis(dichloroboryl)-2-methyl-1-propene 11 affords the 1,1-isobutenyl-bridged bis(1-boratabenzene)zirconium dichloride 7. The X-ray structure of 7 is
1,1-二丁基-1-锡环六-2,5-二烯(8)与1,2-双(二氯硼基)苯9的反应生成交换产物10,该产物在去质子化后与ZrCl 4反应得到非常不稳定的邻苯撑桥联的双(1-硼酸苯)锆二胆酸盐6。来自8和1,1-双(二氯硼基)-2-甲基-1-丙烯11的相似反应序列提供了1,1-异丁烯基桥连的双(1-硼烷苯)二氯化锆7。描述了7的X射线结构。
