Abstract:

The reaction of the Grignard reagent (p-C(6)F(4)H)MgBr with Me(2)SnCl(2) afforded the p-C(6)F(4)H transfer reagent Me(2)Sn(p-C(6)F(4)H)(2) (1). Subsequent reaction of 1 with BCl(3) led to the chloroborane (p-C(6)F(4)H)(2)BCl (2), which was converted to the borane [(p-C(6)F(4)H)(2)BH](2) (3) by treatment with the hydride source Me(2)SiHCl. By reaction of tetrafluoropyridine with i-PrMgCl followed by the in situ reaction with Me(2)SnCl(2), the stannane Me(2)Sn(C(5)F(4)N)(2) (4) could be obtained. However, this did not react with BCl(3). The resulting products were characterized by elemental analyses and NMR spectroscopy. Single crystal X-ray diffraction experiments were performed for compounds 1, 2 and 4. The crystal structure of the literature known compound Me(2)Sn(C(6)F(5))(2) (5) was determined and compared with structures of 1 and 4.
