  • Patent number: 6100428
    Abstract: An improved method for guanylating amines is provided. Broadly, the amines are reacted with a guanylating agent in the presence of a nickel catalyst. Preferably, the nickel catalyst comprises nickel in the zero oxidation state. Suitable nickel(0) catalysts are derived from nickel-boride alloys, nickel-phosphide alloys, aluminum-nickel alloys, nickel on kieselguhr, and nickel on silica/alumina catalysts. Preferred guanylating agents are thioureas and isothioureas. In one embodiment, protecting groups are selectively attached to the guanylating agents to yield particular substituted guanidines. The preferred protecting groups are Boc groups, Cbz groups, and arylsulfonyl groups. The reactions are particularly well suited for guanylating primary and secondary amines. The methods of the invention can be carried out under ambient conditions to provide high yields of the corresponding guanidines, with the nickel catalyst being essentially completely recoverable for reuse.

    Abstract: There are described dyeing compositions for keratin fibres, and in particular for human hair, containing a dyestuff of the formula: ##STR1## in which A denotes an alkylene group, an alkylene group substituted by one or more OH groups, or an alkylene group interrupted by a hetero-atom such as oxygen or by an --NH-- group, R.sub.1 and R.sub.2, which are identical or different, denote hydrogen, alkyl, monohydroxyalkyl or polyhydroxyalkyl, or R.sub.1 and R.sub.2 can together form a heterocyclic ring chosen from among piperidino or morpholino groups, Y denotes alkoxy or NO.sub.2, R denotes hydrogen or lower alkyl, and if Y denotes alkoxy, Z denotes NO.sub.2 and is located in the para-position to the amine group, and if Y denotes NO.sub.2, (a) Z denotes alkoxy or OH and is located in the para-position to the NO.sub.2 group, or alternatively (b) Z denotes OH and is located in the para-position to the amine group, and also their cosmetically acceptable salts. Many of these dyestuff are novel.
