methyl (Z)-O-methylbenzothiohydroximates were prepared either by reaction of the corresponding (Z)-N-methoxybenzenecarboximidoyl bromides with potassium fluoride in dimethyl sulfoxide, or by reaction of N-methoxybenzamides with Lawesson’s reagent followed by alkylation. Irradiation of the Z isomers led to a photostationary equilibrium containing mixtures of approx. 40% E and 60% Z, from which the E isomers
通过相应的 (Z)-N-甲氧基苯甲酰溴与氟化钾在二甲亚砜中的反应,或通过 N-甲氧基苯甲酰胺与劳森试剂反应然后烷基化来制备一系列甲基 (Z)-O-甲基苯并硫代羟肟酸盐。Z异构体的辐照导致含有约。40% E 和 60% Z,从中分离出 E 异构体。
