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.

Anticancer activity of organotin(IV) carboxylates

Inorganica Chimica Acta, 2014
Abstract This article provides a critical review of the anticancer activity of organotin(IV) carboxylates in the last five years. Most of the organotin(IV) carboxylates discussed in this review have greater anticancer activity against different cell lines than do the standard drugs.

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

Chemistry and applications of organotin(iv) complexes of Schiff bases

Dalton Transactions, 2011
Schiff bases are the most widely used versatile ligands, able to coordinate many elements and to stabilize them in various oxidation states. Recently, this class of compounds has been employed as models for biological systems, and in control of stereochemistry in six-coordinate transition metal complexes.

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(

Performance Study of Organotin (IV) Complexes

International Journal of Organic and Inorganic Chemistry, 2018
Organotin(IV) complexes possess at least one covalent carbon to organotin bond as part of its structural characteristics [1]. It also contains tin in a +4 oxidation state bonded to donor atoms of a number of ligands. They have received a lot of research interests due to their structural diversity and numerous applications [2].
