5171-99-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5171-99-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,7 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5171-99:
(6*5)+(5*1)+(4*7)+(3*1)+(2*9)+(1*9)=93
93 % 10 = 3
So 5171-99-3 is a valid CAS Registry Number.

Exploring the Influence of Phosphine Ligation on the Gold-Catalyzed Hydrohydrazination of Terminal Alkynes at Room Temperature

Rotta-Loria, Nicolas L.,Chisholm, Alicia J.,MacQueen, Preston M.,McDonald, Robert,Ferguson, Michael J.,Stradiotto, Mark

, p. 2470 - 2475 (2017)

The synthesis and/or NMR/X-ray characterization of a new series of (L)AuCl complexes is reported, featuring BippyPhos, AdJohnPhos, silyl ether based ligands including OTips-DalPhos, and PAd-DalPhos. These complexes, along with previously reported analogue

Ancillary ligand-free copper catalysed hydrohydrazination of terminal alkynes with NH2NH2

Peltier, Jesse L.,Jazzar, Rodolphe,Melaimi, Mohand,Bertrand, Guy

supporting information, p. 2733 - 2735 (2016/02/19)

An efficient and selective Cu-catalysed hydrohydrazination of terminal alkynes with parent hydrazine is reported. The methodology tolerates a broad range of functional groups, allows for the synthesis of symmetrical and unsymmetrical azines, and can be extended to hydrazine derivatives and amines.

, p. 6844 - 6848 (2014/06/09)

A number of saturated abnormal N-heterocyclic carbene (NHC) complexes of gold, in combination with KBArF4 as activator, were successfully applied in the chemoselective addition of hydrazine to alkynes. The reaction proceeds even at r

Anti-Bredt N-heterocyclic carbene: An efficient ligand for the gold(i)-catalyzed hydroamination of terminal alkynes with parent hydrazine

Lopez-Gomez, Maria J.,Martin, David,Bertrand, Guy

supporting information, p. 4483 - 4485 (2013/06/05)

An anti-Bredt N-heterocyclic carbene gold(i) chloride complex was synthesized by taking advantage of the reversible insertion of the free carbene into the NH bond of hexamethyldisilazane. This precatalyst promotes the parent hydrazine hydroamination of te

Gold-catalyzed hydroamination of alkynes and allenes with parent hydrazine

Kinjo, Rei,Donnadieu, Bruno,Bertrand, Guy

supporting information; experimental part, p. 5560 - 5563 (2011/07/30)

A diverse array of nitrogen-containing compounds were formed by the addition of hydrazine to alkynes, diynes, enynes, and allenes in the presence of cationic gold(I) complexes with a cyclic (alkyl)(amino)carbene ligand (see scheme; the X-ray crystal structure of the gold-hydrazine complex is shown). This hydroamination is an ideal initial step for the preparation of acyclic and heterocyclic bulk chemicals. Dipp=2,6-diisopropylphenyl. Copyright
