    摘要: 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.
