Abstract
Compound trans-[FeH(CN)(dppe) 2] ( 1) reacted with alkyl iodides or alkyl bromides to give Fe(II)–organic isocyanide complexes of the type trans-[FeH(CNR)(dppe) 2]X [X=I: R=Me ( 2), Et ( 3), Pr ( 4), CH 2CH 2CH 2I ( 5), i-Pr ( 6), CH 2CHCH 2 ( 7); X=Br: R=Et ( 8), Pr ( 9), n-Bu ( 10), CH 2CH 2Br ( 11), CH 2CHCH 2 ( 12), CH 2CCH ( 13)]. Compound 1 reacted with BF 3 to give a Lewis acid–base adduct, trans-[FeH(CN→BF 3)(dppe) 2]. Compounds 5 and 13 were characterized structurally by X-ray diffraction, in which the hydride ligand appears to be involved in the dihydrogen bonding, MH⋯HC.
