Abstract: Compounds of Formula I, and their N-oxides and agriculturally suitable salts, are disclosed which are useful for controlling undesired vegetation wherein R1 is cyclopropyl optionally substituted with 1-5 R5, isopropyl optionally substituted with 1-5 R6, or phenyl optionally substituted with 1-3 R7; R2 is ((O)jC(R15)(R16))kR; R is CO2H or a herbicidally effective derivative of CO2H; R3 is halogen, cyano, nitro, OR20, SR21 or N(R22)R23; R4 is —N(R24)R25 or —NO2; j is 0 or 1; and k is 0 or 1; provided that when k is 0, then j is 0; and R5, R6, R7, R15, R16, R20, R21, R22, R23, R24 and R25 are as defined in the disclosure. Also disclosed are compositions comprising the compounds of Formula I and a method for controlling undesired vegetation which involves contacting the vegetation or its environment with an effective amount of a compound of Formula I.

Abstract: An approach is provided for generating mercury (II) sulfide from elemental mercury. Elemental mercury is injected into a reaction vessel containing vaporized sulfur. The elemental mercury reacts with at least a portion of the vaporized sulfur to form the mercury (II) sulfide.
