Abstract
Trialkylstannanes R(3)SnH (R = Me, Bu) and 9-BBN add to the B=N double bond in dimethylaminobis(trifluoromethyl)borane (CF3)(2)B=NMe(2) (A) to yield (CF3)(2)BH.NMe(2)SnR(3) and (CF3)(2)BH.NMe(2)-9-BBN respectiv ely. Both hydrolyse to yield the dimethylamine adduct of bis(trifluoro methyl)borane (CF3)(2)BH.NHMe(2) (I). Treatment of I with KOH in ether gave the salt K[(CF3)(2)BHNMe(2)] (Ia). The nitrogen in Ia has been a lkylated with CH3I, ClCH(2)Ph, ClCH2CH=CH2 and BrCH2C drop CH to yield the respective amine boranes (CF3)(2)BH.NMe(3) (II), (CF3)(2)BH.NMe(2 )CH(2)Ph (III), (CF2)(2)BH.NMe(2)CH(2)CH=CH2 (IV) and (CF3)(2)BH.NMe(2 )CH(2)C drop CH (V), whereas ring opening of 2-phenyloxirane led to (C F3)(2)BH.NMe(2)CH(2)CH(OH)C6H5 (M). I-VI have been characterised by el emental analyses, mass, IR and multinuclear NMR spectroscopy, and the crystal structure of III has been determined by X-ray methods.
