A new tetraorganotin(IV) complex, {bis(µ3-oxo)-bis(µ-isopropoxo)-dichloro-octakis(4-methyl)-tetra-tin, has been synthesized by dimethyltin dichloride in the presence of potassium iso peroxide. This Complex with a general formula of {(CH3)8Sn4Cl2(C3H7O)2O2} is classified in the category of tetraorganodistannoxanes. Solid state crystal structure of this compound was determined by single crystal...
Reduction of an N-heterocyclic carbene (NHC) adduct of SnCl(2), viz. [(IPr)SnCl(2)] (IPr = :C{N(Dip)C(H)}(2); Dip = 2,6-diisopropylphenyl), with a magnesium(I) dimer, has afforded the first NHC complex of a row 5 element in its diatomic form, [(IPr)Sn=Sn(IPr)]; a computational analysis of the complex indicates that it comprises a singlet state, doubly bonded tin(0) fragment, :Sn=Sn:, datively b...
[reaction: see text] Nanometer tin-mediated allylation of aldehydes or ketones in distilled or tap water gave rise to corresponding homoallyl alcohol in high yield without any other assistance such as heat or supersonic or acidic media.
X-ray diffraction studies reveal the structure of {[(2-C(6)H(5)-1,2-C(2)B(10)H(10)-1-COO)Bu(2)Sn](2)O}(2), 1, to conform to the common motif found for {[(R'COO)R(2)Sn](2)O}(2) compounds. The dimer features a central Bu(2)Sn(2)O(2) unit (two-fold symmetry) with the two Bu(2)Sn groups being linked via bridging oxygen atoms, each of which also carries an exocyclic Bu(2)Sn moiety. The two pairs of ...
