Arylation of organotin halides with pentaarylantimony and pentaphenylbismuth
Pentaarylantimony and pentaphenylbismuth arylate oranotin halides R3SnX and R2SnX2 (R = Alk, Ar; X = Cl, Br) in toluene at room temperature to aryltin derivatives R3SnAr and R2SnArX (initial reagent molar ratio 1:1) or R2SnAr2 (2:1) in 78-95% yield.
Ueber Tetraaryl-Methan-Analoga in der Gruppe 14. II. Ph4-nSi-p-Toln und Ph4-nSn-p-Toln (n = 0 bis 4): Einfluss der p-Tolyl-Substituenten auf Struktur und NMR-chemische Verschiebungen
The title compounds have been synthesized by Li and Grignard reactions.The crystal structure of Ph3Si-p-Tol has been determined.The substitution of only one phenyl by one p-tolyl group causes only a slight deviation from the ideal S4 symmetry of Ph4Si.Gra
