Abstract
Alkyl bis(2,6-dimethyl-4-methoxyphenyl)boranes((DMP) 2BR) have been synthesised in an attempt to overcome the limitations of the steric hindrance approach to the production of boron stabilised carbanions. Anion production from (DMP) 2BR, followed by alkylations and condensations with aldehydes are reported. Reduction of (DMP) 2F with potassium hydride yields the corresponding hydroborate. Attempts to isolate (DMP) 2BH were unsuccessful but the borane was readily trapped with alkynes, yielding alkenylboranes. The allyl derivative, (DMP) 2BAllyl, was made and some of its reactions were investigated.
