    Description / Table of Contents: Mechanism of the Thermal Isomerisation of O-2-Butenyl O,O-Dimethyl Thiophosphate. Kinetic StudyThe thermal isomerisation of O-2-butenyl O,O-dimethyl thiophosphate (1b) (scheme 3) obeys first order rate law. Solvent polarity does not affect the parameters of activation, but influences a little the rate constants. The kinetic data and the observed “special” salt effect lead to the conclusion that the isomerisation proceeds by a dissociative mechanism. Ion pairs as intermediates are proposed.
    Notes: Die thermische Isomerisierung von Thiophosphorsäure-O-2-butenylester-O,O-dimethylester (1b) (Schema 3) verläuft nach einem Geschwindigkeitsgesetz 1. Ordnung. Die Polarität des Mediums beeinflußt nicht die Aktivierungsparameter und übt lediglich einen minimalen Einfluß auf die Geschwindigkeitskonstanten aus. Die kinetischen Daten und der festgestellte „spezielle“ Salzeffekt lassen den Schluß zu, daß diese Isomerisierung einem intramolekularen ionischen Mechanismus folgt. Als ionische Zwischenstufe werden Ionenpaare postuliert.

    Description / Table of Contents: Thiophosphatidic Acid Esters Containing a C—S—P BondThiophosphatidic acid and the following thiophosphatidic acid esters containing a C—S—P bond were synthesized: O,O-dimethyl S-(2,3-distearoyloxypropyl) thiophosphate (4). O-methyl S-(2,3-distearoyloxypropyl) thiophosphoric acid (4a), and O,O-bis(trimethylsilyl) S-(2,3-distearoyloxypropyl) thiophosphate (6). The structures were proved by NMR and IR spectra. It was demonstrated that O,O-dimethyl S-(2,3-isopropylidenedioxypropyl) thiophosphate (3) can be obtained from 2,3-isopropylidenedioxy-1-propanethiol (1) in good yield and acylated to yield 4.
    Notes: Thiophosphatidsäure und folgende Thiophosphatidsäureester mit C—S—P-Bindung wurden synthetisiert: Thiophosphorsäure-O,O-dimethyl-S-(2,3-distearoyloxypropyl)ester (4), Thiophosphorsäure-O-methyl-S-(2,3-distearoyloxypropyl)ester (4a) und Thiophosphorsäure-O,O-bis(trimethylsilyl)-S-(2,3-distearoyloxypropyl)ester (6). Die Strukturen wurden durch NMR- und IR-Spektren bestätigt. Es wurde gezeigt, daß Thiophosphorsäure-O,O-dimethyl-S-(2,3-isopropylidendioxypropyl)ester (3) mit guter Ausbeute aus 2,3-Isopropylidendioxy-1-propanthiol (1) erhalten und zu 4 acyliert werden kann.
