Al-H-C chemistry

The synthesis of LAI(OH)(2), LAI(SH)(2), LAI(SeH)(2), and LAI(NH2)(2) (L = HC(CMeNAr)(2), Ar = 2,6-iPr(2)C(6)H(3)) is described. For the preparation of LAI(SH)(2) from LAIH(2) in the presence of sulfur a catalyst is required, whereas LAI(OH)(2) and LAI(NH2)(2) are obtained in the presence of a N-heterocyclic carbene as a HCl acceptor. The starting material for the latter reaction is LAICl(2). The organometallic hydroxides are environmentally friendly, in comparison to the metal halides, due to their OH functionality resembling that of water. The compounds are interesting precursor for the preparation of heterobimetallic compounds e.g. LAI(mu-S)(2)ZrCP2.
