There is provided a single vessel process for the preparation of a pyridine dicarboxylate compound of formula I ##STR1## via the sequential condensation of an alkyl vinyl ether with Vilsmeier reagent, oxalacetate and an ammonia source.

The present invention provides a process to prepare a pyridine-2,3-dicarboxylate derivative via the reaction of a dailkyl alkoxy(or alkylthio)oxalacetate with an appropriately substituted acrolein compound in the presence of an ammonia source and a solvent. The present invention also provides useful intermediate compounds of formula IV. ##STR1##

There is provided a method to overcome or decrease the antagonistic interaction caused by the application of an acetohydroxyacid synthase-inhibiting herbicide in combination with a non-acetohydroxyacid synthase-inhibiting herbicide such as dicamba, 2,4-D, bromoxynil, atrazine or bentazone, which comprises applying an effective amount of imazapyr (2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)nicotinic acid).

The present invention provides a process for the preparation of microcapsule compositions, methods for using those microcapsule compositions, compositions containing those microcapsule compositions and microcapsules prepared by the process of the present invention.

There is provided a single step procedure to prepare 2-aryl-5-perfluoroalkylpyrrole derivatives directly from the perfluoroacetylated Strecker reaction product. Said pyrrole derivatives are insecticidal and also useful as precursors to other insecticidal arylpyrrole compounds. Further provided are amide nitrile intermediates, useful in the preparation of insecticidal arylpyrrole compounds.

There is provided a method for the control of pyrethroid-resistant insects and the protection of animals therefrom which comprises contacting said insects with a toxic amount of a formula I arylpyrrole compound. ##STR1##

There is provided a process for the preparation of 2-aryl-5-(perfluoroalkyl)pyrrole compounds from N-(perfluoroalkylmethyl)arylimidoyl chloride compounds. The 2-aryl-5-(perfluoroalkyl)pyrrole compounds are useful for the control of insect and acarid pests, and may also be used to prepare other pesticidal arylpyrrole compounds. In addition, the present invention provides N-(perfluoroalkylmethyl)arylimidoyl chloride compounds which are useful as intermediates in the preparation of arylpyrrole comp...

The apparatus comprises a base unit, a rotatable shaft extending vertically from the base unit, a means for rotating the shaft, and a rotatable cylindrical basket capable of holding fried foods. The basket comprises an horizontally disposed circular bottom piece and a vertically disposed cylindrical piece of porous material being attached at its lower open end to the outer edge of the circular bottom piece to form the vertical wall of the basket. The basket is vertically connectible to and remov...
