Abstract
Reaction of the acetylenic-bridged ditin precursor [Me3-SiCH2(Cl2)SnCH2(Me2)Si]2C2 1 with the oxygen source (But 2SnO)3 results exclusively in formation of the dimeric tetraorganodistannoxane {[Me3SiCH2(Cl)SnCH2(Me2)SiCCSi(Me2)CH2Sn(Cl)CH2SiMe3]O}2 2 which has the hitherto unknown cis-configuration; this is retained during the quantitative conversion of 2 into the hydroxy-substituted analogue {[Me3SiCH2(OH)SnCH2(Me2)SiCCSi(Me2)-CH2Sn(Cl)CH2SiMe3]O}2 3.Keywords
