dextrorotatory enantiomer of a configurational difetialone stereoisomer, composition comprising the same, rodenticidal bait, method for controlling harmful target rodents, and chromatographic process.

摘要

the invention relates to a dextrorotatory enantiomer of the configurational difetialone stereoisomer, referred to as a homo-stereoisomer of formula 3- (4'-bromobiphenyl-4-yl) -1- (4-hydroxythiocoumarin-3-yl) -1,2, 3,4-tetrahydronaphthalene, wherein the carbon atoms 1 and 3 of the 1,2,3,4-tetrahydronaphthalene group of said homo-stereoisomer have the same absolute configuration.
