Abstract

NEW MATERIAL:An α-aralkylidene (or alkylidene)-β-phenylthio-γ-butyrolactone compound I (R1 is H or lower alkyl; R2 is ≤10C alkyl or phenyl; R1 and R2 may forma pentamethylene chain).
EXAMPLE: α-Benzylidene-β-phenylthio-γ-butyrolactone.
USE: Germicides, insecticides and synthetic intermediates for butenolide-type natural materials, e.g. callic acid, etc..
PROCESS: A compound I is prepared by the thermal dehydration of an α-substituted-β-phenylthio-γ-butyrolactone compound II in the presence of an acid catalyst.
