Ueber 2, 6-Dimethylpyrimidin-Derivate

Pirimicarb: 2-dimethylamino-5,6-dimethylpyrimidin-4-yl dimethyl­carbamate

In the title compound, C(11)H(18)N(4)O(2) (systematic name: 2-dimethyl-amino-5,6-dimethyl-pyrimidin-4-yl N,N-dimethyl-carb-amate), the pyrimidine ring and dimethyl-amino group are almost in the same plane, making a dihedral angle of 1.6 (1)°. The dihedral angle between the mean plane of the pyrimidine ring and that of the dimethyl-carbamate group is 83.42 (5)°. In the crystal structure, inter-m...

irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...

Synthesis, Characterization, in vitro Antimicrobial, and Anthelmintic Evaluations of N-(4, 6-dimethylpyrimidin-2-yl)-4-((2-hydroxynaphthalen-1-yl) diazenyl) Benzene Sulfonamide and Its Metal (II) Complexes

As a part of systematic investigation of biologically active compound, new azo dye ligand N-(4, 6-dimethylpyrimidin-2-yl)-4-((2-hydroxynaphthalen-1-yl) diazenyl) benzene sulfonamide has been synthesized by diazotization of 4-amino-N-(4, 6-dimethylpyrimidin-2-yl) benzenesulfonamide and coupled with coupling compound, naphthalen-2-ol. A new series of Ni (II), Cu (II), and Zn (II) complexes derive...

Flüssigkristalline aromatische Cholesterin-Derivate

Die Cholesterin-Abkömmlinge lieferten im letzten Jahrhundert die ersten bekannten Flüssigkristalle [1], Weil sie leichter zugänglich waren und ein höheres Verdrillungsvermögen besaßen als andere bekannte chirale Flüssigkristalle (z. B. Abkömmlinge des natürlichen sekundären Amylalkohols), stellten sie bis weit in die siebziger Jahre dieses Jahrhunderts auch die wichtigste Quelle für chirale Flü...
