Tris(triphenylsiloxo)-thiovanadium(V) is a complex organometallic compound with the chemical formula [V(Si(C6H5)3)3S]. It consists of a vanadium(V) center coordinated to three triphenylsiloxo ligands and a sulfur atom. The triphenylsiloxo ligands are derived from triphenylsilanol (Si(C6H5)3OH), where each phenyl group is a benzene ring. tris(triphenylsiloxo)-thiovanadium(V) is of interest in organometallic chemistry due to its unique structure and potential applications in catalysis and materials science. It is characterized by its stability, thermal properties, and reactivity, which can be influenced by the electronic and steric effects of the ligands. The compound's synthesis typically involves the reaction of vanadium(V) chloride with triphenylsilanol and sulfur, followed by careful control of reaction conditions to achieve the desired product.

Check Digit Verification of cas no

The CAS Registry Mumber 18891-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,9 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18891-71:
(7*1)+(6*8)+(5*8)+(4*9)+(3*1)+(2*7)+(1*1)=149
149 % 10 = 9
So 18891-71-9 is a valid CAS Registry Number.

Oxo and Thiovanadium(V) Thiolates

Preuss, Fritz,Noichl, Harald

, p. 121 - 129 (2007/10/02)

Syntheses of oxovanadium(V) thiolates such as O = V(SR)3 (R = tC4H9, SiPh3) and O = V(OtC4H9)n(StC4H9)3-n (n = 1, 2) are described.The thiovanadium(V) compounds S = V(OtC4H9)3, S = V(StC4H9)(OtC4H9)2 and S = V(SSiPh3)3 have been prepared by various methods: substition using Lawesson reagent, oxidation of V(OtC4H9)4 by sulfur, or disproportionation reaction of VCl4 with LiSSiPh3; O = V(OSiR3)3 (R = Me, Ph) undergoes a reaction with Lawesson reagent to yield dithiophosphonate complexes.All compounds obtained are characterized by 1H and 51V NMR spectroscopy; the stability of thiovanadium(V) compounds is discussed.V(StC4H9)4 has been sythesized as a first example of vanadium(IV) thiolates. - Key words: Thiolato Oxovanadium(V), Thiolato Thiovanadium(V), Preparation, 51V NMR Spectra
