Studies of organotin(IV)-orthoquinone systems

Journal of Organometallic Chemistry, 1998
Abstract The primary process in the reaction of hexaphenylditin with various substituted orthoquinones (Q) is shown to involve attack by the quinone at a phenyl ligand. The intermediate thus formed decomposes to yield Ph3Sn(SQ·), where S(Q·−) is the corresponding semiquinonate.

Di- and tri-organotin(IV) diphenyldithiophosphinates

Journal of Organometallic Chemistry, 1987
Abstract Di- and tri-organotin(IV) diphenyldithiophosphinates, R 2 Sn(S 2 PPh 2 ) 2 (R  Me, n-Bu, Bz, Ph) and R 3 SnS 2 PPh 2 (R  Me, Cy, Bz, Ph) were prepared by reaction of the corresponding organotin chlorides or oxides with diphenyldithiophosphinic acid or its ammonium salt. All the compounds were characterized by IR and 1 H NMR spectra. For

Tin(IV) and organotin(IV) derivatives of novel β-diketones

Inorganica Chimica Acta, 1997
Abstract A series of new tin(IV) and organotin(IV) derivatives has been synthesized. In basic (triethylamine) chloroform solution five- [R 2 SnCl(Q * )] and six-coordinate [R 2 Sn(Q * ) 2 ] tin(IV) derivatives (HQ * =1-phenyl-3-methyl-4-trichloroacetylpyrazol-5-one; R=Ph, Bz) are obtained. In basic (KOH) alcoholic R′OH solution (R′=Me, Et) [R 2 Sn(

Organotin(IV) N,N-disubstituted dithiocarbamates

Journal of Organometallic Chemistry, 1967
Compounds with general formulas R3Sn(SSCNR′2 (REt, Ph, R′) or R2Sn(SSCNR′2)2 (Rhalogen, Et, Ph; R′Et, Ph) were prepared and their physical data are reported and discussed. In X2SN(SSCNEt2)2 an octahedral cis coordination of the tin atom is shown to be present with a chelated dithiocarbamato moiety.

Organotin(IV) polypyrazolylborates I. Tris(pyrazolyl)borates

Journal of Organometallic Chemistry, 1989
Abstract The compounds SnCl 3 Q, RSnX 2 Q and XSnR 2 Q have been prepared (Q = pz 3 BH − ; X = Cl or Br; R = Me, Et, Bu or Ph). According to the 1 H, 13 C and 119 Sn NMR spectra in acetone or dichloromethane, the tin is six-coordinate in the trichloro- or dichloro-tin(IV) derivatives, but it may reach a lower coordination number in the ...
