摘要:

AbstractMethods are described by which various organolithium species are reacted with triphenylborane to generate materials possessing borate functionality. Comparison is made between experiments involving simple alkyllithium compounds, and those involving living anionic polybutadienes. Evidence is presented to show that using living polybutadienes at temperatures below 0°C, the reaction proceeds with very high efficiency, and that overall conversion to borate‐functionalised polymer is virtually quantitati
