General Description

1,3-Bis-(chlorodimethylstannyl)-propane, also known as bis(dimethylchlorostannyl)propane, is a chemical compound with the formula (CH3)2SnCl-CH2-CH2-SnCl(CH3)2. This organotin compound is used as a precursor for the synthesis of various organic compounds, including polymers, and as a reagent in organic synthesis. It is also a potential reagent for the production of dimethyltin dichloride. However, due to its toxicity and potential environmental impacts, the use and handling of 1,3-Bis-(chlorodimethylstannyl)-propane require careful attention to safety precautions and regulations.

1,5,9-Tristannacyclododecanes as lewis acids. Novel structure of a chloride complex

A simple procedure for the preparation of substituted 1,5,9-tristannacyclododecanes RRSn-(CH2)3SnRR′(CH2) 3SnRR(CH2)3 {R = R′ = CH3 (3); R = CH3, R′ = Cl (4); R = R′ = Cl (5)} is described. Their complexing behavior toward chloride was investigated by means of 119Sn NMR spectroscopy. Both 4 and 5 yielded evidence for complex formation but behaved differently from each other. A complex {(5Cl)(Ph3P=N=PPh3)+} (6) was isolated; its structure as determined by single-crystal X-ray diffraction shows that 5 acts as a bidentate Lewis acid via unsymmetrical transannular bridging by a chloride ion. 6 crystallizes in the monoclinic space group P21/c with the unit-cell dimensions a = 11.691 (2) ?, b = 24.652 (4) ?, c = 17.353 (4) ?, β = 72.70 (1)°, V = 5110.6 ?3, and D(calcd) = 1.65 g/cm-3 for Z = 4. The structure was refined to a final R value of 0.039 for 4003 independent reflections.
