Pb. Hitchcock et al., NOVEL SN-II-AG-I REACTIONS FROM SN[CH(SIME3)(2)](2) AND AGX (X = NCS,CN, NCO, OR I) - SN-II-AG-I OR (SNX2)-X-IV COMPLEXES, Organometallics, 17(13), 1998, pp. 2686-2688
Treatment of Sn(CHR2)(2) is with the appropriate Ag-I compound in Et2O
at ca. 25 degrees C yielded the heterobimetallic Sn-Ag complexes [GRA
PHICS] (1) and [GRAPHICS] (2) and the oxidative adducts Sn(CHR2)(2)X-2
(X = NCO (3), I (4)). 1 (Ag-Sn = 2.598(1) Angstrom) and 3 have been c
haracterized by X-ray studies, and 1 and 2 provide the first examples
of Sn-119-Ag-109 and Sn-119-Ag-107 coupling in their Sn-119{H-1} NMR s
pectra (R = SiMe3).
