  • Solvent process for hydrolyzing 5-isothiocyano-5,6-dihydrodicyclopentadiene
    Patent number: 4259260
    Abstract: 5-Isothiocyano-5,6-dihydro-dicyclopentadiene is hydrolyzed with caustic to 5-amino-5,6-dihydro-dicyclopentadiene in a reaction medium comprising a polar organic liquid which is inert under the reaction conditions and which at least partially dissolves the reactants and products.

  • Metal salts of 1,1,5,5-tetrasubstituted dithiobiurets as population control agents
    Patent number: 4011318
    Abstract: Disclosed are compounds useful as population control agents which are metal salts of 1,1,5,5-tetra-substituted dithiobiurets of the formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3 and R.sup.4, when taken independently of each other are selected from the group consisting of C.sub.1 -C.sub.18 alkyl, C.sub.6 -C.sub.12 aryl, C.sub.3 -C.sub.12 cycloalkyl, and these radicals substituted by at least one member of the group consisting of hydroxyl, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.8 acyl, halo and nitro, and R.sup.1 and R.sup.2, when taken together along with the nitrogen to which they are bonded, and R.sup.3 and R.sup.4 when taken together with the nitrogen to which they are bonded, are selected from the group consisting of N-morpholinyl, N-piperidyl, N-pyrrolidyl and N-aziridinyl.
