methyl-tin bond was selectively cleaved from aryltrimethyltin compounds by sodium metal in liquidammonia. The triorganyl-stannyl anions thus obtained are arylated by chloroarenes by means of photostimulated SRN1 reactions. Such reactions can be repeated to replace all methyl groups by different aryl groups. The one-pot synthesis of asymmetric triarylmethyltin compounds can be achieved from trimethyltin
