摘要： Disclosed is a ruthenium-phosphine complex represented by formula (I):�{RuX(L)}.sub.2 (.mu.-X).sub.3 !.sup.- �R.sub.2 NH.sub.2 !.sup.+(I)wherein R is hydrogen, an alkyl group having 1 to 5 carbon atoms, a cycloalkyl group, a substituted or unsubstituted phenyl group or a substituted or unsubstituted benzyl group; X is halogen; and L is an optically active or inactive tertiary phosphine. A process for preparing the complex (I) is also disclosed, which comprises (A) reacting a ruthenium complex represented by formula: �RuX(arene)(L)!X (wherein arene is a substituted or unsubstituted phenyl group) and an ammonium salt represented by formula (III): R.sub.2 NH.HX, or (B) reacting a ruthenium complex represented by formula: �RuX.sub.2 (arene)!.sub.2, a tertiary phosphine represented by L, and an ammonium salt (III). The complex (I) useful as a catalyst for general syntheses or asymmetric syntheses can be obtained easily in good yield.

摘要： A syringe is arranged with a frangible connection between a conical needle head mounting a needle member to permit removal of the head and associated needle member permitting projection of the needle into the syringe body subsequent to its use. A modification of the invention includes a container to receive used needle bodies, with indicator dye contained within the capsule within the needle body that is ruptured upon insertion of the needle therewithin for indication of a used needle within a storage container.

摘要： An optically active 2-diphenylphosphinomethyl-2'-diphenylphosphinyl-1,1'-binaphthalene derivative represented by the following general formula (I) ##STR1## wherein R represents a phenyl group, a tolyl group, an anisyl group or a chlorophenyl group, and a process for the production of optically active substances in which the above compound and a transition metal compound are used. The asymmetric diphosphine of the present invention is related to the creation of novel compounds, which is excellent as a ligand for asymmetric synthesis use. When the above compound is used together with a transition metal compound such as of ruthenium, rhodium or the like, it shows markedly excellent properties as the catalyst of asymmetric hydrogenation and the like reactions, in terms of selectivity, conversion ratio, catalytic activity and the like.
