摘要: Novel polynuclear organometallic complexes useful as catalysts for the reversible deshydrogenation of alkanes and alkane group are disclosed. The novel compounds comprise a first transition, a second transition metal p-bonded to an ?5-aromatic ligand, and a pincer ligand. The pincer ligand comprises a 6p-electron aromatic ring having at least 2 ring atoms in an 1, 3 relationship bonded each to a neutral Lewis base through a bridge, the bridge being a diradical. The pincer ligand binds the first transition metal through each of the Lewis bases and through the ring atom adjacent to both Lewis bases and p-coordinates the second transition metal through all aromatic ring atoms. The first transition metal may also bond to 2 or 4 hydrogen atoms.

摘要: For converting hydrocarbons, particularly by cracking and dehydrogenation, react hydrocarbons at 225*-800*C, particularly 300*-600*C, in contact with a soluble catalyst in liquid phase, said catalyst comprising a compound of a metal of group Ib, IIb, IVa, Va, VIa, VIIa or VIII and a reducing agent, particularly one of formula Al Hn X3 n with n 1 or 2, X OR, NR2, NHR or SR, R being a monovalent organic radical, or one of formula Me (Al HmX''4 m )p wherein m is 1, 2 or 3, p is the valence of Me,i.e., of a metal of group Ia or IIa, and X'' is R, OR, NR2, NHR or SR.
