Benzyltrialkyl-(1-13) and benzyltriphenylstannanes (16)(17)(18)(19)(20)(21)(22) have been easily prepared in a one-pot synthesis via coupling reaction of benzyl bromide derivatives (C 6 H 5 CH 2 Br andPr, Bu, and Ph) in THF/H 2 O (NH 4 Cl) medium mediated by zinc powder. Such coupling also occurs with (Bu 3 Sn) 2 O. Dibenzyldibutylstannane (15) is prepared by reaction of benzyl bromide with Bu 2 SnCl 2 or (Bu 2 SnCl) 2 O, and (2-naphthylmethyl)tributylstannane (14) by reaction of 2-(bromomethyl)naphthalene with Bu 3 SnCl. 13 Cand 119 Sn-NMR data are reported for all compounds, and Mo ¨ssbauer data for benzyltributylstannanes 10 and 11 and benzyltriphenylstannanes 16-18 and 20-22. The crystal structures of Ph 3 SnBn, with Bn ) o-(17) and m-ClC 6 H 4 CH 2 (18) and o-(20) and m-FC 6 H 4 -CH 2 (21) have been determined.

The 1,1′‐bis(chlorostannyl)‐substituted ferrocenes Fe(C5H4–SnMe2Cl)2 (2), Fe(C5H4–SnMeCl2)2 (3) and Fe(C5H4–SnCl3)2 (4) were prepared, starting from 1,1′‐bis(trimethylstannyl)ferrocene (1). Treatment of the chlorides with Li[AlH4] afforded the 1,1′‐bis(hydridostannyl)‐subsituted ferrocenes Fe(C5H4–SnMe2H)2 (5), Fe(C5H4–SnMeH2)2 (6) and Fe(C5H4‐SnH3)2 (7), respectively. All complexes 1–7 were studied by 1H‐, 13C‐, and 119Sn‐NMR spectroscopy with 1D and 2D techniques. The compounds 1–4 were investigated by temperature‐dependent 119Sn‐ and 57Fe‐Mössbauer spectroscopy. The electrochemistry of 1–5 gave evidence of reversible one‐electron oxidation processes. The molecular structure of 1,1′‐bis(trichlorostannyl)ferrocene (4) was determined by X‐ray structural analysis, and there was no indication of intra‐ or intermolecular Sn···Cl···Sn interactions. This direct structural information proved to be consistent with both the Mössbauer and the solution NMR spectroscopic data.
