The reaction between alkyl ethaneimidothioate hydrohalides (1-alkylthioethaniminium halides) and organic halides gives unsymmetrical sulfides in good yields under liquid-liquid phase-transfer conditions.
The present invention provides compounds of formula (I) wherein R1, R2, A, X, D1, D2 and Y3 are as defined in the claims. The invention further provides intermediates used in the preparation of these compounds, to compositions which comprise these compounds and to their use in agriculture or horticulture for controlling or preventing infestation of plants by phytopathogenic microorganisms, preferably fungi.
The time-dependent isomerizations and thiol additions of several Z- and E-monounsaturated fatty acid methyl esters catalyzed by alkanethiyl radicalsduring gamma-radiolysis of tert-butylalcohol solutions are analyzed on the basis of the radiation chemical yield of radicals and established rate data. This provides room-temperature rate constants for the reversible thiyl addition. Within experimental
