Abstract:

Treating 1-(dialkylamino)-2,5-dihydro-1H-boroles (alkyl = Me, Et) with a hindered Li amide in THF gave 70-71% borole dianions (I; R = Me, Et). Treating I (R = Me, Et, CHMe2) with Me2NCH2CH2NMe2 (TMEDA) in THF gave 94-97% cryst. adducts. The structure of one of these (II) was detd. by x-ray crystallog.
