Olefin metallation provides an efficient route to novel unsaturated boracarbocycles. Thus the first 3,7-dimethylene-1,5-diboracyclooctanes R2NB[CH2C( = CH2)CH2]2BNR2 (R = Et, (i)Pr) and the first 3,4-dimethyleneboracyclopentanes activated CH2C(= CH2)C(= CH2)CH2BNR2 (R = Et, (i)Pr) have been made by treatment of dichloro(dialkylamino)boranes with [Li(TMEDA)]2[C(CH2)3] and K2[C2(CH2)4], respectively.
