A NEW PREPARATION OF HEXAALKYLDITINS. 119Sn NMR AND CHROMATOGRAPHIC DATA ON LINEAR POLYTINS
The reaction of triorganotin oxides and formic acid provides a good route to ditin derivatives.Several new linear polytin compounds have been isolated, and the vicinal and long range 119Sn-119Sn coupling constants determined.A linear relationship has been demonstrated between the logarithm of the HPLC retention time and the number of tin atoms in the compounds.
