Carbon-13 NMR studies of some organotin(IV) compounds. Al-Allaf, Talal A. K. (Coll. Sci., Univ. Mosul, Mosul, Iraq). J. Organomet. Chem., 306(3), 337-46 (English) 1986. CODEN: JORCAI. ISSN: 0022-328X. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 22 The 13C chem. shifts and 13C-119Sn,117Sn coupling consts. for several organotin(IV) compds. RxSnCl4-x (R = Me, Bu, Ph; x = 1-4) have been measured in both inert (CDCl3) and donor (DMSO-d6) solvents, as have 13C data for RxSnR'4-x (R = Me, Ph, R' = Bu; R = Me, R' = Ph; x = 1-3) and Me3SnX (X = pseudohalide). 6452-61-5 and 1461-25-2 which are cas registry numbers are also used here. The d and 1J(C-Sn) values appear to depend mainly on the type and no. of substituents on tin and the donor ability of the solvent. There are linear relationships between the no. of substituents (x), and both d and 1J(C-119Sn) for almost all the RxSnX4-x series (R = Me, Bu, Ph, X = Cl; R = Me, Bu, X = Ph; x = 1-4), when measured in a single solvent, e.g. CDCl3. There is an excellent linear relationship between 1J(C-119Sn) and 2J(1HC-119Sn) for the compds. MexSnCl4-x. Detn. of 13C data for Me3SnCl and Ph3SnCl in a range of solvents reveals that the value of 1J(C-Sn) increases with the donor ability of the solvent. The marked increase in the values of 1J(C-119Sn) in DMSO-d6 for RxSnCl4-x (R = Me, Bu, Ph) on going progressively from x = 4 to x = 1 suggest tin coordination nos. of 4, 5, 6 and 6, resp. Some addnl. phys. data are presented for the isolated complexes formed from DMSO and PhxSnCl4-x (x = 1-3) and Me3SnX (X = N3, O2CMe). .
