| Abstract: | Organoantimony Compounds. VI. Crystalline Phenyl Antimony. Formation and Cleavage with Sodium and Lithium Butyl, respectively Reactions of C6H5SbH2 with C6H5CH ? CH2, C6H5C ? CH and other unsaturated compounds give the corresponding hydrogenated system and phenyl antimony as orange-red crystals and the formula (C6H5Sb)6 · 1 C6H6 1.1 reacts with sodium by cleavage of Sb–Sb bonds forming C6H5SbNa2 and C6H5(Na)Sb–Sb(Na)C6H5. These stibides are suitable materials to prepare tert. stibines, distibines and cyclic stibines. The cleavage of 1 with butyllithium is a complicated reaction and gives beside other stibides also C6H5(C4H9)SbLi which can be characterized as (CH3)3Si–Sb(C4H9)C6H5. The 1H-nmr data of the prepared stibines are discussed. |
