    Abstract: A platinum complex represented by the formula: wherein R is a (C1 - 18) alkyl group, a (C1 - 18)-alkenyl group or a group @@ -X @@R in which X is -CH=CH- or a (C1 - 5) alkylene group, and R is a phenyl group, a hydroxyphenyl group, a (C7 - 12) alkoxyphenyl group, a halogenophenyl group, a nitrophenyl group, or (C8 - 13) alkoxycarbonylphenyl group, a cyclohexyl group having a (C1 - 5) alkyl substituent, R is a (C1 - 18) alkyl group, R is a hydrogen atom, or R and R are linked together to form a (C2 - 7) alkylene group; R is OH or NO3; the dotted line indicates that the bond may be either a single bond or a double bond; the chain line indicates a conjugated system; n is a number of from 1 to 2, and the 1,2-diaminocyclohexane moiety has a cis- trans- l - or trans-d-configuration. This platinum complex is useful in the treatment of tumors.

    Abstract: PURPOSE:The catalytic hydrogenation of p-formylbenzoic ester in the presence of ammonia is conducted by using a Raney nickel catalyst which is prepared by developing a Raney alloy containing 36-44wt% of nickel to produce title compound. CONSTITUTION:A binary Raney nickel alloy of 36-44wt% nickel and aluminum is developed to form a nickel catalyst. The catalytic hydrogenation of p-formylbenzoic ester is conducted together with ammonia in an amount of 3-6 times the amount of the ester in the presence of the above Raney nickel catalyst in 5-15% by volume as the powder/weight of the ester. The Raney alloy is developed by adding the powdery alloy to an aqueous sodium hydroxide solution under controling the emission of heat, washing with water, ethanol, then anhydrous ethanol, finally centrifuging.
