Synthesis and crystal structures of new complexes of di- and tribenzyltin 2-amino-1-cyclopentene-1-carbodithioates

Treatment of dibenzyltin dichloride with 1 equiv. of 2-amino-1-cyclopentene-1-carbodithioic acid (ACDA) gave Bz2SnCl(ACDA) 1. Reaction of two equivalents of ammonium 2-amino-1-cyclopentene-1-carbodithioic acid (AACD) with Bz2SnCl2 and then recrystallization from THF produced Bz2Sn(ACDA)2 · THF 2. Bz3Sn(ACDA) (3) was obtained from reaction of Bz3SnCl with 1 equiv. of AACD. The products were characterized by IR and NMR (1H, 13C, 119Sn) spectroscopy, elemental analysis and X-ray crystallography.
