Recent progress on arsenic-containing functional polymers

Tetrachlorocatecholates of triarylarsines as a novel class of Lewis acids

“…We have been developing practical synthetic methods that give various kinds of organoarsenic compounds from non-volatile arsenic precursors. 11…”

Systematic Study of Pnictogen-Fused Heterofluorenes

“…The traditional synthesis of arsoles requires arsenic chlorides , or hydrides, which are highly toxic and volatile, whereas practical synthetic routes for phosphole, stibole, and bismole have all been well established. To address this issue, we have been developing practical synthetic strategies for organoarsenic compounds, in which nonvolatile arsenic precursors and intermediates are employed . Diiodoarsines, which can be generated in situ by the addition of iodine (I 2 ) to cyclooligoarsines, are key synthetic intermediates for the arsole backbone .…”

“…Diiodoarsines, which can be generated in situ by the addition of iodine (I 2 ) to cyclooligoarsines, are key synthetic intermediates for the arsole backbone . Since the first report on diiodoarsines in 2015, we have reported the synthesis, structures, and photophysical and electronic properties of numerous arsole derivatives …”

4-Aryldithieno[3,2-b:2′,3′-d]arsoles: effects of the As-substituent on the structure, photophysical properties, and stability

“…1–3 Among a variety of heteroatoms, arsenic is an element that has gradually gained attention in recent years. 4 Although dangerous precursors, which are volatile and toxic, were previously necessary to synthesize organoarsenic compounds, recent progress in practical As–C bond formation reactions 5 strongly supports the advancement of As-fused π-conjugated systems. For example, we developed in situ generation of diiodoarsines (RAsI 2 , R = Me or Ph) from cyclooligoarsines such as pentamethylpentaarsine (As 5 Me 5 ) or hexaphenylhexaarsine (As 6 Ph 6 ) (Scheme 1a).…”
