Tetraphenylfluoroantimony(V), with the chemical formula (C6H5)4SbF, is a derivative of antimony, a group 15 post-transition metal. This organoantimony compound features a central antimony atom bonded to four phenyl rings and a fluorine atom. It is a colorless, crystalline solid that is sensitive to air and moisture, and it is typically synthesized by reacting antimony trifluoride with phenylmagnesium bromide. Tetraphenylfluoroantimony(V) is an important precursor in the synthesis of other organoantimony compounds and has potential applications in the fields of organic synthesis, materials science, and as a reagent in chemical reactions. Due to its sensitivity and reactivity, it is crucial to handle tetraphenylfluoroantimony(V) with care, typically under an inert atmosphere or in a controlled environment.

426-77-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 426-77-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 426-77:
(5*4)+(4*2)+(3*6)+(2*7)+(1*7)=67
67 % 10 = 7
So 426-77-7 is a valid CAS Registry Number.

Heavy Pnictogenium Cations as Transmembrane Anion Transporters in Vesicles and Erythrocytes

Park, Gyeongjin,Brock, Dakota J.,Pellois, Jean-Philippe,Gabba?, Fran?ois P.

supporting information, p. 2215 - 2227 (2019/08/08)

Our work on the complexation of fluoride anions using group 15 Lewis acids has led us to investigate the use of these main-group compounds as anion transporters. In this paper, we report on the anion-transport properties of tetraarylstibonium and tetraary

The structure of tetraarylantimony halides and tetraphenylantimony isothiocyanate

Sharutin,Sharutina,Pakusina,Smirnova,Pushilin

, p. 108 - 114 (2008/10/09)

X-ray diffraction analysis is used to study tetraphenylantimony fluoride (I), tetra-p-tolylantimony (II), and tetraphenylantimony isothiocyanate (III), where Sb atom has a distorted trigonal-bipyramidal coordination. The Sb-C bond lengths in I-III lie a range of 2.102(1)-2.183(1) A; the Sb-F, Sb-Cl, and Sb-N distances are equal to 2.0530(8) A, 2.7319(7) A, and 2.507(2)A, respectively, in I, II, and III.

Catalytic C-phenylation of methyl acrylate with tetraphenylantimony(v) halides and carboxylates

Gushchin,Grunova,Moiseev,Morozov,Shavyrin,Dodonov

, p. 1376 - 1379 (2007/10/03)

Catalytic C-phenylation of methyl acrylate to methyl cinnamate with the Ph4SbX complexes (X = F, Cl, Br, OH, OAc, O2CEt) in the presence of the palladium compounds PdCl2, Pd(OAc)2, Pd2(dba)3, Pd(Ph3P)2Cl2, and Pd(dppf)Cl2 (dba is dibenzylideneacetone and dppf is bis(diphenylphosphinoferrocene)) was studied in organic solvents (MeCN, THF, DMF, MeOH, and AcOH). The highest yield of methyl cinnamate (73% based on the starting organometallic compound) was obtained for the Ph4SbCl- PdCl2 (1:0.04) system in acetonitrile.
