The synthesis of optically active p‐anisyl‐(3‐hydroxy‐3‐methylbutyl)methyl‐α‐naphthyl tin (IV) is described. The spectroscopic properties of this compound and of the products used as synthesis intermediates are given. The two diastereoisomers of (‐)‐menthyl‐β‐(methylnaphthyl‐phenylstannyl)‐propionate (V) could not be separated. Copyright © 1975 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim

Abstract The configurational instability of triorganotin halides RR′RSnX, which is a second order process with respect to added nucleophiles (S) such as pyridine, can be rationalized in terms of a two-step process involving an attack by S at tin to displace X, followed by a rate-determining attack of the second S molecule at the metal atom to give an achiral petacoordinate-complex. This conclusion follows the estimation of the equilibrium constant of the first step, by measurement of the rate of...

Abstract Determination of the concentrations of pyridine required to cause coalescence of the neophylic methyl group resonances at 60, 100 and 270 MHz has shown that the racemisation of methylneophyl-t-butyltin chloride or bromide in benzene is of second order in the nucleophile.
