64443-05-6 Usage
Reaction
Useful catalyst for the Ullmann synthesis.
Catalytic asymmetric [2,3]-Sigmatropic rearrangement of sulfur ylides.
Precatalyst for enantioselective N–H insertion reactions with diazoesters and anilines.
Uses
Tetrakis(acetonitrile)copper(I) hexafluorophosphate can be employed as a catalyst for the synthesis of triazolo[1,2-a]indazole-1,3,8-trione and 2H-indazolo[2,1-b]phthalazine-trione derivatives by the reaction of aryl aldehydes, dimedone and urazole or phthalhydrazide, respectively. It can also be used as a copper precursor:For the formation of Cu2S/CdS nanorod junctions by cationic exchange process.To synthesize monometallic copper macrocyclic biquinazoline ligand [Cu(Mabiq)].To prepare the cuprous complex [Cu(2-iQBO)(POP)]PF6]; where 2-iQBO=2-(1′-isoquinolyl)benzoxazole and POP=bis[2-(diphenylphosphino)phenyl]ether, which can form luminescent pseudo-polymorphs.For the synthesis of [Cu(NHC)2]PF6 complexes [(NHC = N-heterocyclic carbene] which can be further used in the hydrosilylation of carbonyl compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 64443-05-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,4,4 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 64443-05:
(7*6)+(6*4)+(5*4)+(4*4)+(3*3)+(2*0)+(1*5)=116
116 % 10 = 6
So 64443-05-6 is a valid CAS Registry Number.

, p. 15531 - 15535 (2019)
New simple, fast, effective and environmentally friendly one-pot method for the synthesis of extensively used tetrakis(acetonitrile)copper(i) complexes with BF4-, PF6- and ClO4- counterions is invented and optimized. The approach suggested allows using water as solvent and minimizes amounts of toxic organic reagents in the synthetic protocol.
Intermittent molecular shuttle as a binary switch
Jiang, Lasheng,Okano, Junji,Orita, Akihiro,Otera, Junzo
, p. 2121 - 2124 (2004)
Action stations: Treatment of rotaxanes containing a 2,2′-bipyridine moiety between two bipyridinium stations with Cu1 ions gives rise to a new type of shuttling process. The switch between static and dynamic states is achieved through complexation of the Cu1 center to the 2,2′-bipyridine unit followed by decomplexation (see picture).
