- Efficient conversion of sulfones into β-keto sulfones by N-acylbenzotriazoles
-
Acyclic sulfones 4a-f and alicyclic sulfone 7 react with readily available N-acylbenzotriazoles 3a-g (derived from aliphatic, aromatic, and heteroaromatic carboxylic acids) to provide the corresponding β-keto sulfones 5a-n and 8a-c, respectively, in good

A compound having the formula STR1 wherein R is C1 -C4 alkyl, cyclopropyl, C2 -C4 alkoxyalkyl, C4 -C8 dialkylaminoalkyl, C2 -C4 alkylthioalkyl, C2 -C4 alkylsulfinylalkyl, C2 -C4 alkylsulfonylalkyl, phenyl, C7 -C9 aralkyl, C7 -C9 alkaryl, furyl, thienyl or pyridyl; R1 is hydrogen or C1 -C4 alkyl; R2 is hydrogen or C1 -C4 alkyl; R3, R4 and R5 are the same or different and are hydrogen or C1 -C4 alkyl; R6 and R7 are the same or different and are hydrogen, C1 -C4 alkyl, allyl, benzyl or tolyl with the proviso that both R6 and R7 are not hydrogen; and n is 0, 1 or 2 and methods of making same are disclosed. This compound is useful as a pesticide. Intermediates useful in synthesizing this pesticidally effective compound are also taught. These intermediate compounds have the structural formulas STR2 where R, R1, R2, R3, R4, R5 and n have the same meanings as the pesticidally effective compound recited above; and Q is a leaving group. Methods of making these intermediate compounds are described.
