Reduction of the anti-Bredt bishydrazone 4,9-dimethyl-2,3,7,8-tetra-azatetracyclo[7.3.1.0.4,1206,10]trideca-1,6-diene with lithiumaluminium hydride–aluminium chloride or by catalytic hydrogenation gives the bishydrazine 1,6-dimethyl-2,3,7,8-tetra-azatetracyclo[7.3.1.0.4,1206,10]tridecane, but reaction with either lithiumaluminiumhydride or aluminium chloride gives dihydropyrazoles by ring cleavage

4,8-Dimethylbicyclo [3,3,1]nona-3,7-diene-2,6-dione with hydrazine gives a tetracyclic bishydrazonehavingtwodoublebonds at bridgehead positions; the chemistry of hydrazo-and azo- compounds derived from this bishydrazone is described.
