| 520 | 3 | |a A series of C,O‐chelated organotin(IV) alkoxides, L2PhSnOtBu (4), L2PhSnOMe (6), L2Sn(OtBu)2 (11), and siloxides L2PhSnOSiPh3 (3), L2Sn(OSiPh3)2 (10) (L=[2‐(CH2O)2CH]C6H4), was prepared by salt elimination reactions. They were obtained from the organotin(IV) iodides L2PhSnI (1) or L2SnI2 (2) upon reactions with tBuOK, MeONa or Ph3SiONa, respectively, in dry THF or methanol. Under non‐inert conditions, compounds 4 and 6 undergo combined hydrolysis and condensation to give the hexaorganodistannoxane (L2PhSn)2O (5). The stannoxane 5 is easily hydrolysed to L2PhSnOH (7), which quickly converts back when heated. Basic hydrolysis of diiodide 2 produces the cyclic oxide (L2SnO)3 (8). Its reaction with an equimolar amount of Ph3SiONa gives only a mixture of the expected L2SnI(OSiPh3) (9), 10 and the precursor, 2. Yet, 8 shows a unique reactivity pattern when combine with m‐tolyl boronic acid, affording stannaboroxane (L2SnO)2OB(m‐tol) (12). All the isolated species were characterised in solution by NMR spectroscopy and mass spectrometry. The solid‐state molecular structures of 1–5, 10–12 were established by single‐crystal X‐ray diffraction (XRD). Additionally, thermogravimetric analysis of 3–5, 8, 10, and 12 was conducted. | |
