Abstract: The present disclosure is directed to a process for the preparation of a compound having the formula: wherein R is unsubstituted or substituted C1-C12alkyl, unsubstituted or substituted C2-C4alkenyl, unsubstituted or substituted C2-C4alkynyl, unsubstituted or substituted C3-C6cycloalkyl, unsubstituted or substituted aryl, unsubstituted or substituted heteroaryl, or —SR1; R1 is unsubstituted or substituted C1-C12alkyl, unsubstituted or substituted C2-C4alkenyl, unsubstituted or substituted C2-C4alkynyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted aryl or unsubstituted or substituted heteroaryl; and X is a selected leaving group that is not halogen, and may specifically be methylsulfonate, trifluoromethylsulfonate, and p-toluenesulfonate. These compounds are valuable intermediates useful in the synthesis of compounds having pesticidal activity.

Abstract: A process for the preparation of a compound of the formula and, where applicable, its E/Z-isomers, mixtures of E/Z-isomers and/or tautomers and acid addition products thereof, in each case in free form or in salt form, wherein: R is unsubstituted or substituted C1-C12alkyl, unsubstituted or substituted C2-C4alkenyl, unsubstituted or substituted C2-C4alkynyl, unsubstituted or substituted C3-C6cycloalkyl, unsubstituted or substituted aryl, unsubstituted or substituted heteroaryl, or —SR1; R1 is unsubstituted or substituted C1-C12alkyl, unsubstituted or substituted C2-C4alkenyl, unsubstituted or substituted C2-C4alkynyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted aryl or unsubstituted or substituted heteroaryl; and X is a leaving group; The process comprises reacting a compound of the formula: with a halogenating agent or a sulfonylating agent.
