  Abstract In this research, an investigation of the isomerization and the applications of 3-phospholene oxides were elaborated. The isomerization of 3-phospholene oxides to 2-phospholene oxides was investigated under thermal condition. The application of bases and acids was also tested in this reaction. Moreover, the isomerization was also elaborated via the formation of halophosphonium salt intermediates

  retroaddition strategy for the generation of phosphinidenes involves thermal and photochemical decomposition of 1-arylphosphiranes and photolysis of 1-aryl-3-phospholenes. Evidence that free phosphinidenes are produced as reactive intermediates includes a lack of dependence of the conversion rate on precursor and substrate concentrations and the nature of the reaction products. These are best rationalized by the

  New platinum complexes of the type cis-Pt(L)(2)Cl-2 have been synthesized from five- and six-membered cyclic phosphines, which were prepared after deoxygenating a series of phosphine oxides (3-phospholene oxides, phospholane oxides, a 1,4-dihydrophosphinine oxide, and a 1,2,3,6-tetrahydrophosphinine oxide). The complexes were characterized by NMR and mass spectral data, and their stereostructures were

  Disclosed is a light colored modified isocyanate mixture and a preparation method thereof. The method comprises the following steps: a) reacting isocyanate groups of a raw material isocyanate under the action of a phospholenecatalyst, and finally obtaining a modified isocyanate reaction solution containing carbodiimide and/or uretonimine derivatives; and b) adding a compounded terminator of a halosilane organic and a sulfonic anhydride to the reaction solution obtained in step a so as to terminate the reaction of carbodiimidization. The modified isocyanate prepared by the method has the characteristics of a liquid state at room temperature, being stable in storage at room temperature and high temperature, and low color number.
