Abstract
1 -Diisopropylamino-3-borolene is readily lithiated by tert-butyllithium in THF to produce lithium (1-diisopropylaminoborolenediide), the second known example of the 6 π-electron borole dianion. Trimethylsilylation of the dianion gives trans-1-diisopropylamino-4,5-bis(trimethylsilyl)-2-borolene. Reaction with [{C6(CH3)6}RuCl2]2 affords the (borole)-ruthenium complex [C6(CH3)6]Ru[C4H4BN{CH(CH3)2}2].Keywords
