Abstract

NEW MATERIAL:A derivative of 4-methyl-3-allyl-3-penten-2-one of formula I (R=alkyl, aryl; R1=H, lower alkyl, lower alkenyl; n=0, 1, 2).
EXAMPLE: 3-Allyl-4-methyl-5-benzenesulphenyl-3-penten-2-one.
USE: Intermediate of allethrolone which is a component of pyrethroid insecticides. The corresponding insecticides are almost harmless to mammals and plants but show excellent insecticidal effects for insects. RPOCESS:E.g. a derivative of 4-methyl-3-sulphenyl-3-allyl-4-penten-2-one of formula II is subjected to allyl rearrangement to give 5-sulphenyl-4-methyl-3-allyl-3-penten- 2-one of formula V which is then oxidized to afford a compound of formula VI (n=1, 2).
