Abstract
Bis-(monothiolic acid ester) alkali earth metal salts (I; R1, R2=alkyl, haloalkyl, M=divalent alk. earth metal), useful as intermediate for manufacturing agricultural fungicides and insecticides, were prepd. by reaction of II, S, and a divalent alk. earth metal hydroxide (or oxide). Thus, (EtO)2 POH 138.0, s 32.0, and Ca(OH)237.0g were stirred for 2hr at 80-85≰C to give I(R1=R2=Et, M=Ca) with 88.9% yield.
