Abstract

The triorganotin halides (CabC,P)SnMe2X (2a, X = Cl; 2b, X = Br) and a tetraorganotin compound (Cab C,P)SnMe3 (7), containing the o-carboranylphosphino ligand (CabC,P), have been prepared by the reaction of LiCabC,P (1) with Me2SnX2 and Me2SnCl, respectively. 1H 13C, 31P, and 119Sn NMR spectroscopy indicate that the tin centers in 2a and 2b are pentacoordinate as a result of intramolecular Sn-P coordination, whereas the tin center in 7 is tetracoordinate. The substitution reactions of 2a using Nal, NaN3, NaCpFe(CO)2, and NaB(CN)H3 afforded the substituted products (CabC,P)SnMe2X (3, X = I; 4, X = N3; 5, X = CpFe(CO)2; 6, X = H). The Wurtz-type coupling reaction of 2a with sodium afforded the distannane.The reaction of the distannane 10 with Pd2(dba)3-CHCl3 afforded the bis(stannyl)palladium complex 11. When compounds 2a and 2b were employed in the reaction with Pd2(dba)3, the halo-bridged metal complexes 12a and 12b were isolated. The crystal structures of 9b, 11, and 13 were determined by X-ray structural studies. As a result of the Sn-P interaction, the tin atom in 9b exhibits a distorted trigonal-bipyramidal configuration.
