Correlation relationships of molar refraction and ten topological indices for 47 organotin compounds

Journal of Environmental Sciences 1997年第1期9卷 100-107页

作者： Dai Shugui Huang Guolan Sun Hongwen Department of Environmental Science,Nankai University,Tianjin 300071,China Department of Environmental Science Nankai University Tianjin 300071 China

Correlation relationships of 10 topological indices and molar refraction for 47 struc- turally-complicated organotins which included 16 ionic compounds R_mSnX_(4-m) and 31 covalent ones R_4Sn that is 41 aliphatic compounds(15 unsaturated and 26 saturated)and 6 aromatic ones were *** of these ten topological parameters for describing the structure of elemental or- ganic compounds was then evaluated according to the correlation *** lately improved molecular connectivity indices(MCIs)-radius-corrected MCI ~1X^r and bond-length-corrected MCI ~1X^b were applied and proved to be most suitable for the structure expression in QSA(P)R studies of organotins or other elemental organic compounds.

关键词： QSA(P)R organotin compounds topological parameters bond-length-corrected MCI radius-corrected MCI.

　　The study of ionic organotin compounds is of current attention owing to their diversified molecular structures and wide range of applications, such as biological activities[1 ～3] and as catalysts in organic synthesis. [4] Recently, we synthesized some new ionic organotin compounds by dephenylation reaction. [5] In this paper, we continued to study the reaction of mercaptoacetic acid with phenyltin trichloride in the presence of organic base. The reaction equation was as follows:……

Synthesis, Characterization and Crystal Structure of (Z)-1-[2-(Triarylstannyl)vinyl]-1-indanols and Their Arylha-lostannyl Derivatives

引用

Chinese Journal of Chemistry 2004年第4期22卷 348-353页

作者：朱东升吕春胜梅泽民高伟张越涛母瀛王宗睦 School of Chemistry Jilin University

Z)-1-[2-(Tri-o-tolylstannyl)vinyl]-1-indanol (1) and (Z)-1-[2-(tri-p-tolylstannyl)vinyl]-1-indanol (2) were syn-thesized by the addition reaction of 1-ethynylindanol with tri-o-tolyltin and tri-p-tolyltin hydride. The aryl groups in compound 1 and 2 were substituted by Br2 or I2 to yield monohalide derivatives (36). The compounds 16 were characterized by elemental analysis, 1H NMR and FT-IR spectroscopy. The crystal structures of 1, 2 and 4 have been determined by single crystal X-ray diffraction analysis. The Sn atom in 1 and 2 exhibits a tetrahedral geometry distorted towards trigonal bipyramid due to a weak intramolecular interaction between Sn and the hydroxyl O atoms [0.2839(4) nm and 0.2744(5) nm], while the Sn atom in 4 adopts a trigonal bipyramidal geometry with a significant O→Sn(1) interaction [0.2552(5) nm].

Chinese Journal of Chemistry 1998年第1期16卷 22-27页

作者：黄葵傅方信潘华德 Department of Chemistry Northeast Normal University Changchun Jilin 130024 China Current address: Department of Chemistry Southern Illinois University at Carbondale IL. USA.

(E)-[(2-Cyclohexenyl)vinyl]triaryltin (aryl=phenyl, p-tolyl) were synthesized and characterized by elemental analysis, IR, H-1 NMR spectroscopy. The crystal structure of (E)-[(2-cyclohexenyl)vinyl]triphenyltin was also determined by the X-ray diffraction. Experiments show that this compound has the conjugated system, which makes it have possible bioactivity and antitumor activity.
