Preparation of Some Higly Polarised Ethenes by the Addition of Amines to Suitable Carbonitriles

Elvidge, John A.,Judson, Philip N.,Percival, Albert,Shah, Raksha

, p. 1741 - 1744 (2007/10/02)

Substituted diaminomethylene derivatives of malononitrile (2) and of cyanoacetamides, cyanoacetates, and cyanothiolacetates (4) - (6) have been prepared from amine salts of tricyanomethane (1) and of related anions (3) having one ester or amide function in place of a cyano group.

Multinuclear magnetic resonance spectroscopy of spin-admixed S = 5/2, 3/2 iron(III) porphyrins

Boersma, Arden D.,Goff, Harold M.

, p. 581 - 586 (2008/10/08)

A variety of synthetic iron(III) porphyrin complexes (FeIIIPorX, X = SO3CF3-, ClO4-, and C(CN)3-) were examined with multinuclear NMR spectroscopy (1H, 13C, 19F, and 35Cl). Deviations from NMR Curie law behavior, diminished magnetic moments, and characteristic ESR g = 4 values support previous evidence for the quantum-mechanical admixture of S = 5/2 and S - 3/2 states. NMR studies of titrations with the corresponding tetrabutylammonium salts and dipolar shift calculations show the ligands are coordinated rather than ion paired in solution. Solvent studies indicate more S = 5/2 character is present in aromatic solvents than in chlorinated solvents. Although the tricyanomethanide complex is thought to exhibit a "pure" S = 3/2 state in crystalline form, solution measurements are consistent with spin admixture.

3-Aminoisothiazole derivatives as herbicides

-

, (2008/06/13)

A new class of herbicidal compounds consisting of 1-alkyl- and 1,1-dialkyl-3-(4-substituted-3-amino-5-isothiazolyl)ureas and N-(4-substituted-3-amino-5-isothiazolyl)-alkanamides, in which the 4-substituent consists of cyano and carbamoyl, exhibits preemergence and postemergence herbicidal activity, controlling effectively the growth of a wide spectrum of grassy and broad-leaved plant species. The synthesis of members of this class is described in detail, and the utility of representative compounds is exemplified.

A new class of herbicidal compounds consisting of 1-alkyl- and 1,1-dialkyl-3-(4-substituted-3-alkoxy-5-isothiazolyl)ureas and N-(4-substituted-3-alkoxy-5-isothiazolyl)alkanamides, in which the 4-substituent consists of alkoxycarbonyl, cyano and carbamoyl, exhibits preemergence and postemergence herbicidal activity, controlling effectively the growth of a wide spectrum of grassy and broad-leaved plant species. The synthesis of members of this class is described in detail, and the utility of representative compounds is exemplified.
