F-19 NMR-STUDY OF THE POLARIZATION DIRECTION AND POLARITY OF TIN-HYDROGEN AND TIN-TRANSITION METAL BONDS IN TRIS(4-FLUOROPHENYL)STANNANE AND ITS ORGANOMETALLIC DERIVATIVES
Dn. Kravtsov et al., F-19 NMR-STUDY OF THE POLARIZATION DIRECTION AND POLARITY OF TIN-HYDROGEN AND TIN-TRANSITION METAL BONDS IN TRIS(4-FLUOROPHENYL)STANNANE AND ITS ORGANOMETALLIC DERIVATIVES, Russian chemical bulletin, 43(11), 1994, pp. 1822-1826
A series of (4-FC6H4)(3)SnML(n) compounds containing tin-transition me
tal bonds were synthesized. Based on F-19 NMR data for these compounds
, (4-FC6H4)(3)SnSn(C6H4F-4)(3), and (4-FC6H4)(3)SnH, conclusions were
drawn concerning the polarization direction and relative polarity of t
he tin-hydrogen and tin-metal bonds in the above compounds and in the
hydrides L(n)MH and R(3)SnH. It was found that, in the general case, t
he group electronegativities of the L(n)M groups do not vary similarly
to the electronegativities of the central metal atoms.
