Primary and Secondary Vinylarsines: Synthesis, Stability and Characterization
摘要:
Primary unsaturated arsines, vinylarsine (1a), isopropenylarsine (1b), (Z+ E)-prop-1-enylarsine (1c), and secondary divinylarsine (1d) are synthesized by reaction of arsenic trichloride with vinyltributylstannane derivatives 2a-c followed by a chemoselective reduction of the corresponding chloroarsines 3a-d Compounds 1a-d are characterized from their spectral data and tungsten complex derivative (1a). The arsines 1 exhibit a low stability at room temperature even in a solvent (tau1/2 ca. 30 min).
