ChemInform Abstract: ETHERIFICATION OF ARSINE OXIDES WITH DIOLS

Abstract

Das Arsinoxid (I) gibt mit den α‐Diolen (II) die 1,3,2‐Dioxa‐arsolane (IIIa)‐(IIIe).

Synthesis, Spectroscopic and Structural Systematics of Complexes of Germanium(IV) Halides (GeX4, X = F, Cl, Br or I) with Phosphane Oxides and Related Oxygen Donor Ligands

“…In a similar way, GeBr 4 andMe 3 AsO gave Me 3 AsBr 2 . The conversion of R 3 AsO to R 3 AsCl 2 has been reported to be achieved by a number of reagents including MeCOCl,27 COCl 2 ,28 PCl 3 and AsCl 3 ,29 and with aqueous HCl,30 but for GeCl 4 to behave in this way under such mild conditions was unexpected, and again contrasts with SnCl 4 which readily forms [SnCl 4 (R 3 AsO) 2 ] adducts 31…”

Complexes of Vanadium(V) Oxide Trifluoride with Nitrogen and Oxygen Donor Ligands: Coordination Chemistry and Some Fluorination Reactions

“…The reaction of VOF 3 2 ] in CH 2 Cl 2 refrigerated for two weeks deposited colourless crystals, which were identified by a crystal structure determination as Ph 3 AsF 2 , showing fluorination of the arsane oxide is possible in this system (VO 2 F may be the other product but this was not identified).The conversion of R 3 AsO to R 3 AsCl 2 is achieved by a number of p-block halides including GeCl 4 , COCl 2 , AsCl 3 and PCl 3 , [25][26][27] but the only prior report of conversion of Ph 3 AsO to Ph 3 AsF 2 is using aqueous HF. [28] The X-ray structure confirms the identity of the product and is in good agreement with the literature data.…”
