REDISTRIBUTION REACTIONS OF DIORGANOTIN DICARBOXYLATES AND DIORGANOTIN DIHALIDES - A CONVENIENT METHOD FOR THE PREPARATION OF HALO-DIORGANOTIN CARBOXYLATES

Organotin compounds with R-2(X)SnL (where R = Me, Et, n-Bu, Ph; L = th e trans-3-(2-furanyl)-2-propenoate anion or the trans-3-(3-methylpheny l)-2-propenoate anion; and X = Cl) have been prepared by redistributio n reactions between the R2SnL2 and R2SnX2 compounds. These compounds w ere characterized by elemental analyses and various spectroscopic tech niques such as H-1, C-13, Sn-119 NMR, Mass, Mossbauer, and IR spectros copies. On the basis of these spectroscopic data, it is suggested that these compounds adopt the cis-R-2(X)SnO2 geometry. (C) 1997 John Wile y & Sons, Inc.
