7422-19-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7422-19-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,2 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7422-19:
(6*7)+(5*4)+(4*2)+(3*2)+(2*1)+(1*9)=87
87 % 10 = 7
So 7422-19-7 is a valid CAS Registry Number.

Solvent- A nd anion-dependent rearrangement of fluorinated carbene ligands provides access to fluorinated alkenes

Hall, Lewis M.,Milner, Lucy M.,Hart, Sam J.,Whitwood, Adrian C.,Lynam, Jason M.,Slattery, John M.

supporting information, p. 17655 - 17659 (2019/12/23)

The construction of fluorocarbene ligands within the coordination sphere of transition metal complexes using sequential nucleophilic and electrophilic addition to a vinylidene complex is described. Reaction of [Ru(η5-C5H5)(dppe)(CCPhF)][N(SO2Ph)2] with [NMe4]F results in nucleophilic attack of fluoride at the metal-bound carbon of the vinylidene ligand to give alkenyl complex [Ru(η5-C5H5)(dppe)(-CFCFPh)]. Subsequent eletrophilic fluorination with N-fluorobenzenesulfonimide (NFSI) results in the formation of the fluorinated carbene complex [Ru(η5-C5H5)(dppe)(CF-CHFPh)][N(SO2Ph)2]. The fluorocarbene complexes undergo rearrangement to liberate free fluorinated alkenes, a process governed by the choice of solvent and anion, representing a new metal-mediated route to fluorinated alkenes from alkynes.

Tellier, Frederique,Sauvetre, Raymond,Normant, Jean-F.

, p. 23 - 30 (2007/10/02)

An overall retention of configuration is observed during the chlorodesilylation of (Z)-1-silyl-1,2-difluoroalkanes, carried out in the presence of fluoride ion and in a polar solvent.
