摘要：
2,4-Bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4- disulfide(Lawesson's Reagent), was refluxed with 3-alkyl glycinamides 1 in anhydrous toluene to yield 1-alkyl-1,3,2-diazaphospholidin-4-thione-2-sulfides 2. The structure was confirmed by elementary analysis, NMR, IR, MS. The results of preliminary bioassay indicated that some of the title compounds possess seletive herbicidal activity.

摘要：
omega-Azolylalkenes 3, 4, and 5 were synthesized by N-alkylation or C-alkylation of omega-bromoalkenes 2, which were obtained either by phase transfer Wittig reactions of omega-bromoalkylphosphonium salts 1 with aldehydes or by Wittig reactions of omega-hydroxyalkylphosphonium salts 6 with aldehydes and subsequent bromination. omega-Azolylalkenes 3 were also directly prepared by the Wittig reaction of omega-azolylalkyltriphenylphosphonium salts 8 with aromatic aldehydes. The stereochemistry of these Wittig reactions tvas studied. (C) 1997 John Wiley & Sons, Inc.

摘要：
The γ-oxo vinyliminophosphorane 3 was prepared for the first time from the Staudinger reaction of vinyl azide 2 and triphenylphosphine. The reactivity of 3 was studied.
