The Effect of Organic Substituents on the Acceptor Properties of TIN (IV) Chlorides

Abstract

<em>The equilibrium constant of adduct formation between some triorganotin chloride of the type R3SnCl (R=C₆H₅, p-CH₃C₆H₄, n-CH₃)CH₂)₃, C₆H₅-CH₂ and Lewis bases Cl¯, Br¯, and I¯, were measured in 50% v/v ethanol-water solvent spectrophotometrically. The average equilibrium constant values for the systems studied shows the following acceptor trend of tin(IV) in the triorganotin chlorides:</em> <em>p</em>-<em>tolyl > n-butyl > Phenyl > benzyl</em> <em>The influence of the organic moieties on the acceptor property of tin(IV) is discussed..</em>
