The present invention provided an improved method for preparing a boratabenzene derivative. The invention includes an improved preparation of 1,4-pentadiyne, 1-haloboracyclohexa-2,5-diene, and 1-methylboracyclohexa-2,5-diene intermediates. These compounds are chemically labile and are not directly isolated from solution. Furthermore, the invention discloses an improved preparation of 1,1-dialkylstannacyclohexa-2,5-diene, another intermediate useful for preparing boratabenzene derivatives.
本发明提供了一种改进的制备硼代苯衍生物的方法。该发明包括改进的1,4-戊二炔、1-卤代硼杂环己二烯和1-甲基硼杂环己二烯中间体的制备方法。这些化合物在化学上是不稳定的,不能直接从溶液中分离。此外,本发明还揭示了一种改进的制备1,1-二烷基锡杂环己二烯的方法,这是制备硼代苯衍生物的另一种有用的中间体。
