Article abstract of DOI:10.1016/0022-328X(82)80003-X

By means of 13C NMR spectroscopy, the coupling constants ¹J(119Sn-13C_Et) of 18 compounds of the SnEt3R type (R = organo group) have been measured.These coupling constants have been shown to reflect the change induced by R in the s-content of the tin hybrid orbitals of the Sn-C_Et bonds.The series of the influence of R obtained on the basis of the coupling constant mentioned as a parameter is compared with a trans-influence series of R obtained on organomercury compounds.Occurring differences are attributed to different modes of bonding of the group R at the central atom.
