Phenyltin trichloride is a chemical compound from the group of organotin compounds .
Extraction and presentation
Phenyltin trichloride can be obtained, among other things, by the reaction of tin tetrachloride with tetraphenyltin ( Kocheshkov rearrangement ):
properties
The physical and chemical properties of monoaryltin trihalides, such as phenyltin trichloride, are similar to those of the corresponding tin tetrahalides.
Physical Properties
Phenyltin trichloride is completely soluble in water, but is only slightly hydrolyzed. It has a flash point of 113 ° C. In the 13 C nuclear resonance spectrum (NMR) it shows the following signals:
Sn – C 1 - | -C 2 | -C 3 | -C 4 | |
---|---|---|---|---|
ppm | 135.8 | 133.9 | 130.3 | 132.9 |
J ( 13 C– 119 Sn) | 1120 | 78.8 | 126 | 121 |
In the 119 Sn NMR it gives a signal at −61.0 ppm. The tin-carbon distance in crystals is 2.12 Å . The molecule has a dipole moment of 4.30 Debye .
Chemical properties
Like other organotin compounds, phenyltin trichloride is a Lewis acid and forms corresponding adducts with bases such as pyridine , piperidine , morpholine or aniline in which the central tin atom is six-coordinate.
By reacting phenyltin trichloride with diethylaluminum hydride in diethyl ether , phenyltin trihydride can be obtained:
