Plumbyl halides

Plumbyl halides with a lead-manganese bond have been prepared by the following dephenylation or demethylation reactions191 ... [Pg.524]

Methyl trimethylsilyl tellurium and phenyl trimethylsilyl tellurium exchanged the organyltelluro group for halogen in reactions with silyl, germyl, stannyl and plumbyl halides. ... [Pg.189]

Germyl, Stannyl, and Plumbyl Anions The preparative methods for the synthesis of the germyl, stannyl, and plumbyl anions are essentially the same as those mentioned above for the silyl anions. The most widely used methods are (1) reduction of halides R3EX (R = alkyl, aryl E = Ge, Sn, Pb X = Cl, Br) with alkali metals and (2) reductive cleavage of the E-E bond of R3E-ER3 (R = alkyl, aryl E = Ge, Sn, Pb) with alkali metals or organolithium reagents. Due to the favorable polarization of the (E = Ge, Sn, Pb) bond, the direct metalation... [Pg.92]

Cyclic pentacoordinate plumbyl anions were synthesized by the oxidative addition of tetraalkylammonium halides to a dithiolatoplumbole (equation 63)79. An X-ray structure analysis of the adduct revealed a monocyclic anionic geometry. [Pg.675]
