Abstract

Hydrolysis products of organotin compounds RC6H4OCH2COOSn(CH(2)ph)(3) (R =o-NO2, 1; m-NO2, 2; p-NO2,3; o-CH3,4; o-OCH3, 5; o-Cl, 6; o-Br, 7) and RC6H3OCH2COOSn(CH(2)ph)(3) (R = o,o-2CH(3),8, O-OCH3, p-CHO, 9; o,p-2Cl, 10), produced in aqueous acetonitrile solution, have been investigated by electrospray mass spectrometry (MS) and MSn techniques. The complexes [Y2SnXR '](-), [Y3SnXR '](-), [Y(3)SnX2R '](-), [Y2SnX3R '](-), and fragment ions of [Y3SnR '](-), plus abundant RC6H4(or RC6H3)OCH2COO- and RC6H4 (or RC6H3)O- ions are observed in negative mode, whereas the protonated molecular ion [M H](+), complexes [Y2SnXR '](+), [Y3SnXR '](+), [Y2SnX2R '](+), [Y3SnX2R '](+), [Y2SnX3R '](+), [Y3SnX3R '](+), as well as [YSnXR '](+), [M-CH(2)ph](), XSn+, (phCH(2))(3)Sn+, phCH(2)Sn(+) (Y = -CH(2)ph, X = -OOCCH2OC6H4R(orC6H3R)) are detected in the positive mode. Water adduct ions are seen in both modes. The assignments are facilitated by agreement between observed and calculated isotopic patterns and tandem mass spectrometry studies.
