  • Process for the preparation of 2-(O-alkyl)-2-thio-1,3,2-oxathiophospholanes
    Patent number: 4877893
    Abstract: A fungicidal composition comprising as active ingredient a 2-(O-[substituted]alkyl)-2-thio-1,3,2-oxathiophospholane of the Formula I ##STR1## wherein R.sub.1,R.sub.2, R.sub.3 and R.sub.4 independently from each other stand for hydrogen, C.sub.1-6 alkyl, C.sub.2-6 alkynyl andX represents halogen, hydrogen, C.sub.1-6 alkyl or mercapto. The process for the preparation of the compounds of the Formula I involves phosphorous pentasulfide, alcohols and pyridine. The compositions are wide spectrum fungicides, particularly useful in combating Sclerotinia sp., Penicillium sp., Alternaria sp., Fusarium sp., Phytophthora infestans and powdery mildew.
