The structure and reactivity of arsenic compounds: Biological activity and drug design

“…Electrochemical results on a number of cyclopolyphosphines [70] indicate that the potential depends on the nature of R rather than ring size, thus indicating there is little or no lone pair delocalisation in the rings. A cyclic polymeric Sb compound has recently been characterised [71], (PhSb)6, isostructural with arsenobenzene. Other linear polymers of the polyarseno compounds are also known [66], e.g.…”

Transfer of polyantimony units

“…The Sb-Sb distances of 2.8381(7)Å to 2.8783(6)Å are in the range of a single bond and in good agreement with other polyantimony ligand complexes. 14,[16][17][18]26 26,27 Complexes containing chair-like or skew boatlike E 6 (E ¼ P, Bi) moieties have also been reported. 28 The most related complex to 1, [(Cp*Ti) 2 (m,h 1:1:1:1:1:1 -P 6 )], was synthesized by the co-thermolysis of [Cp*Ti(CO) 2 ] with white phosphorus.…”

“…10 d Otherwise, only organo-antimony compounds bearing organic substituents ((RSb) 6 , R = C 6 H 5 , C 7 H 7 ) were published. 26,27 Complexes containing chair-like or skew boat-like E 6 (E = P, Bi) moieties have also been reported. 28 The most related complex to 1 , [(Cp*Ti) 2 (μ,η 1:1:1:1:1:1 -P 6 )], was synthesized by the co-thermolysis of [Cp*Ti(CO) 2 ] with white phosphorus.…”

Ring-Collapsed Radical Alternating Copolymerization of Phenyl-Substituted Cyclooligostibine and Acetylenic Compounds

“…Hexaphenylcyclohexastibine (cyclo-(PhSb) 6 ). 25 Preparation of cyclo-(PhSb) 6 was referred to a literature procedure. 11 A solution of 1.0 g (5.29 mmol) of bis(cyclopentadienyl)cobalt(II) in 50 mL of THF was added dropwise in the dark to the solution of 2.14 g (7.93 mmol) of dichlorophenylstibine in 50 mL of THF.…”
