Several new tetra-aryltin compounds, Ar4Sn (Ar = 3,5-(CH3)2C6H3, 3,5-Z2C6H3, and m-ZC6H4 (Z = F,Cl] and Ar3SnX [X = Cl, Br, I: Ar = 3,5-(CH3)2C6H3, m- and o-CH3OC6H4; X = Br; Ar = m-ZC6H4 (Z = F, Cl)] have been synthesized by literature methods and complete solution NMR data (119Sn, 13C) are reported for these and other meta- and ortho-substituted aryltins. Meta-substituents appear to exert electronic
