    Abstract: A novel process is described for the homogeneous hydrogenation of nitriles to primary amines utilizing anionic Group VIII metal hydride compositions as catalysts which contain phosphorus, arsenic or antimony organoligands. Use of these anionic catalysts allows the high yield hydrogenation of nitriles to primary amines to be conducted under mild conditions of temperature and pressure with high selectivity and eliminates the need for the presence of ammonia to suppress the formation of significant amounts of secondary and tertiary amines.

    Abstract: Complexes of the titanium cyclopentadienyl compound ##STR1## and nitrogen, having the probable structure: ##STR2## where the symbol N.apprxeq.N represents a bonding state intermediate between the azo-N=N- bond and the hydrazine =N-N= bond; such complex having the simple dimeric form as indicated by molecular weight determination on this form dissolved in tetrahydrofuran, and having a polymeric form wherein a nitrogen atom of one molecule of the dimeric form is coordinated by a dative link with a Ti atom of another molecule of the dimeric form, as suggested by low solubility of this polymeric form in 1,2-dimethoxyethane and breakdown of this form to the dimeric form by action of tetrahydrofuran.Another related complex is a black solid nitrogen-containing reaction product of the above titanium cyclopentadienyl compound in dry state with nitrogen at about 60 atmospheres pressure, having an infrared spectrum typical of a metallocene compound with no N-N or Ti-N vibration absorption bands.The nitrogen in these complexes is reactive, e.g. with reducing agents such as potassium naphthalene, to afford ammonia. Moreover, the complexes are catalytically active for hydrocarbon conversions such as conversion of ethylene to ethane, butane, 1-butene and 1,3-butadiene.

    Abstract: A process is disclosed for making a highly fluorinated aromatic compound by contacting a perfluorocycloalkane, such as perfluorodecahydronaphthalene, with a complex of a metal from Groups IA and IIA of the Periodic Table and an organic electron acceptor. The reaction is carried out in an organic solvent and under reducing conditions which are relatively moderate. Best results are obtained using a perfluorocycloalkane having 2-4 condensed rings and a complex of either sodium or lithium and benzophenone thereby making a perfluorinated condensed ring aromatic compound such as perfluoronaphthalene or perfluorophenanthrene.
