PREPARATION OF MIXED ORGANOTIN CHLORIDES BY REDISTRIBUTION REACTION

Under appropriate reaction conditions, organotin dichlorides with two different alkyl or aryl groups can be prepared in good yields by redistribution between organotin trichlorides and tetraalkyltins or trialkyltin chlorides. Some of these organotin dichlorides have been converted into trialkyltin chlorides with three different alkyl groups by alkylation with tetraalkyltins. The following organotin dichlorides have been prepared: butylmethyl, isobutylmethyl, methylphenyl, ethylphenyl, propylphenyl, butylethyl, and butylpropyl. In addition, butylethylmethyl, butylmethylvinyl, butylethylvinyl, and butyldimethyltin chlorides have been prepared. © 1968, American Chemical Society. All rights reserved.
