Aryltin chlorides and hydrides: Preparation, detailed NMR studies and DFT calculations
摘要:
A series of novel tin chlorides RnSnCl4-n and respective hydrides RnSnH4-n were synthesized displaying a range of substituted phenyl residues, as well as naphthyl moieties (R = Ph, o-tolyl, 2,4-xylyl, 2,6-xylyl, p-biphenyl, 1-naphthyl, 2-naphthyl). These compounds were characterized using H-1, C-13 and Sn-119 NMR spectroscopy. In addition, X-ray diffraction was employed to elucidate the molecular structure of all solid aryltin chlorides (8-10, 14, 15). In each case, the tin is in a distorted tetrahedral environment. All naphthyl containing derivatives exhibit displaced pi-pi stacking. DFT calculations were carried out to compare experimental NMR data with calculated C-13 and Sn-119 shifts, as well as C-13-Sn-119 coupling constants. (C) 2013 Elsevier B. V. All rights reserved.

The synthesis of a series of tetraorganotin(IV) compounds containing selectively the 2-thienyl, 3-thienyl, 5-methyl-2-thienyl, 5-t-butyl-2-thienyl, 4-methyl-2-thienyl and 3-(2-pyridyl)-2-thienyl groups [L], of formula R4-nSn[L]n (R = Ph, p-tolyl, Me, cyclopentyl, cyclohexyl; n = 1–4) is reported. Features of structural interest deduced from 119mSnMössbauer and NMR (13C and 119Sn modes) spectra are
