INSECTICIDE AND NEMATOCIDE

Compounds having the formula in which R is methyl or ethyl, Y is sulfur or oxygen, and R₁ and R₂ are the same or different tertiary alkyl groups each having form 4 to 6 carbon atoms, are insecticides and nematicides, especially for control of soil insects and nematodes.Symmetrical compounds (R₁ = R₂...

Beschreibung
Zusammenfassung:	Compounds having the formula in which R is methyl or ethyl, Y is sulfur or oxygen, and R₁ and R₂ are the same or different tertiary alkyl groups each having form 4 to 6 carbon atoms, are insecticides and nematicides, especially for control of soil insects and nematodes.Symmetrical compounds (R₁ = R₂) may be prepared by reaction of an alkali metal mercaptide with an alkyl (thio) phosphonic dihalide. The alkali metal mercaptide may be prepared by reaction of a tertiary alkyl mercaptan with an alkali metal or alkali metal hydride.
