Abstract

Alkylbis (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 ...
