“…The presence of two nucleophilic nitrogen atoms together with the phosphoryl and carbonyl functional groups led to attractive electronic and structural properties. [4][5][6][7] The hydrazides of phosphorothioic acid esters, diarylphosphinic acid esters of methylphosphonic and methylphosphonothioic acid exhibit pesticidal, bactericidal and fungicidal activities. 8 Quantitative structure-activity relationship (QSAR) equations enabled us to create correlations between the electronic and structural parameters and the inhibition potency.…”

“…The O-alkyl phosphorodichloridothioates were prepared by the esterification of of thiophosphoryl chloride with the appropriate alcohol (70, 77). 0-2,4,5-Trichlorophenyl phosphorodichloridothioate (73) and 0-2,4,5-trichlorophenyl phosphoramidochloridothioates (3) have been reported elsewhere.…”

“…The latter impurities, however, were easily removed by distillation and crystallization techniques. 0-Aryl phosphoramidochloridothioates such as IV, readily prepared from 0-aryl phosphorodichloridothioates and amines (3), are less useful intermediates for the preparation of I and II. The addition of a sodium alkoxide solution to IV dissolved in a suitable solvent gave I in about 25% yields and II in about 50% yields.…”

“…Methylsubstituierte Dihydrazido Verbindungen des Phosphors sind seit längerer Zeit bekannt [1][2][3][4][5][6][7][8][9][10][11][12]. Derartige Substanzen gewinnen neben anderen Phosphor-Hydrazin-Verbindungen zunehmend an Bedeutung; einige zeigten bakterizide und fungizide Eigenschaften oder wurden auf anticarcinogene Wirkung untersucht [1,7]**.…”

“…Derartige Substanzen gewinnen neben anderen Phosphor-Hydrazin-Verbindungen zunehmend an Bedeutung; einige zeigten bakterizide und fungizide Eigenschaften oder wurden auf anticarcinogene Wirkung untersucht [1,7]**. Einige methylsubstituierte Phosphordihydrazide können verwendet werden als Stabilisatoren für Polyurethane [8], hauptsächlich wurden sie aber dargestellt als Ausgangssubstanzen für die Synthese von Heterocyclen, insbesondere anorganischen Heterocyclen [9][10][11][12], Speziell aus der Reihe der von der Thiophosphorsäure abzuleitenden methylsubstituierten Dihydrazide [1,2,8,[9][10][11] [10]. Die Umsetzung von Phenoxy-thiophosphoryl-dichlorid mit Methylhydrazin auf ähnliche Weise ergab dagegen ein Isomerengemisch (3b, 3b-l, 3b-2), wobei vorwiegend 3 b entstand.…”
