Determination of Absolute Signs of 119Sn-117Sn Spin-Spin Coupling Constants

Wrackmeyer, Bernd | Kehr, Gerald

If for a given system two-dimensional (2D) ¹¹⁹Sn/¹H heteronuclear shift correlations can be established for long range coupling constants ⁿJ(¹¹⁹Sn,¹H) (n = 4, 6), absolute signs of coupling constants J(Sn,Sn) are accessible by this technique for the first time. This has been demonstrated for tetrakis(trimethylstannyl)allene (1) with ²J(¹¹⁹Sn,¹¹⁷Sn) (>0) and ⁴J(Sn. 117Sn) (<0) and for tris(trimethylstannyl)phosphane (2) and bis(trimethvlstannyl)- sulfane (3) with ²J(¹¹⁹Sn,¹¹⁷Sn) (<0).
