Herein, we report the syntheses of the water‐soluble organotin compounds [{Me2(H)N(CH2)3}2SnX2]Y2 (1, X = Cl, Y = ClO4; 2, X = F, Y = ClO4) and {Me2(H)N(CH2)3}2SnX4 (3, X = Cl; 4, X = F). The compounds were characterized by elemental analysis, electrospray mass spectrometry, 1H, 13C, 19F, and 119Sn NMR spectroscopy, and in the case of compounds 1, 3 and 4, by single‐crystal X‐ray diffraction analysis. The reaction of compound 2 with fluoride anions in water was investigated by NMR spectroscopy. DFT calculations accompany the experimental work.
The syntheses of the intramolecularly coordinated organotin compounds
{Me2N(CH2)3}Ph(X)SnCH2SnPh2X (3, X = I; 4, X = F)
and {Me2N(CH2)3}Ph(F)Sn(CH2)3SnPh2F (7) are reported.
The compounds have been characterized by elemental analysis, electrospray
mass spectrometry, 1H,1H DOSY (4), 13C, 19F, and 119Sn NMR spectroscopy,
and single-crystal X-ray diffraction analysis. In the solid state,
compound 4 is a head-to-tail dimer as a result of unsymmetrical
Sn–F–Sn bridges, whereas compound 7 is
a monomer with F→Sn intramolecular coordination, giving a six-membered
ring. In solution, both 4 and 7 are monomeric.
The reactions of both 4 and 7 with fluoride
anion in CD2Cl2 have been investigated by variable-temperature 19F and 119Sn NMR spectroscopy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
