Diethyl phosphorochloridothioate

Diazinon is the Ciba-Geigy Corporation trademark name for the active ingredient 0,0-diethyl-0-(2-[l-methylethyl]-4-methyl-6-pyrimidinyl) phosphorothioate. This insecticide is produced commercially by reacting 2-isopropyl-4-hydroxy-6-methylpyrimidine and 0,0-diethyl phosphorochloridothioate (HSDB... [Pg.127]

A series of 0,0-dialkyl-0-2-pyrazinylphosphorothioates and related compounds have been prepared and tested as pesticides. Thionazin (15), the product of reaction of the sodium salt (159) and 0,0-diethyl-phosphorochloridothioate (160) is used in agriculture.360-364... [Pg.181]

The sodium salt of 2-hydroxypyrazine with thiophosphoryl chloride at room temperature gave 2-(dichlorophosphinothioyloxy)pyrazine (1112, 1113) and in N-methyl-2-pyrrolidone with ( ,6)-diethyl phosphorochloridothioate [(EtO)2P(=S)Clj it gave 2-(diethoxyphosphinothioyloxy)pyrazine (1114, 1115), also prepared in the absence of A(-methyl-2-pyrroIidone (1116). The potassium salt of 2-hydroxy-pyrazine in t-butanol-dioxane with 0,0-diphenyl phosphorochloridothioate... [Pg.178]

Other studies involving kinetics include a complex model for the synthesis of 0,0-dimethyl phosphorochloridothioate, the anilinolysis of diphenyl thiophosphinic chloride and of dimethyl and diethyl chloro(thiono) phosphates,and finally the isomerization of anti-apicophilic penta-coordinate phosphoranes having a chelating O-equatorial substituent. ... [Pg.388]
